[CUDA] Improve handling of math functions.
Summary:
A bunch of related changes here to our CUDA math headers.
- The second arg to nexttoward is a double (well, technically, long
double, but we don't have that), not a float.
- Add a forward-declare of llround(float), which is defined in the CUDA
headers. We need this for the same reason we need most of the other
forward-declares: To prevent a constexpr function in our standard
library from becoming host+device.
- Add nexttowardf implementation.
- Pull "foobarf" functions defined by the CUDA headers in the global
namespace into namespace std. This lets you do e.g. std::sinf.
- Add overloads for math functions accepting integer types. This lets
you do e.g. std::sin(0) without having an ambiguity between the
overload that takes a float and the one that takes a double.
With these changes, we pass testcases derived from libc++ for cmath and
math.h. We can check these testcases in to the test-suite once support
for CUDA lands there.

Resubmit "[Tooling] Parse compilation database command lines on Windows."
This patch introduced the ability to decide at runtime whether to parse
JSON compilation database command lines using Gnu syntax or Windows
syntax. However, there were many existing unit tests written that
hardcoded Gnu-specific paths. These tests were now failing because
the auto-detection logic was choosing to parse them using Windows
rules.
This resubmission of the patch fixes this by introducing an enum
which defines the syntax mode, which defaults to auto-detect, but
for which the unit tests force Gnu style parsing.

[MS] Silence -Wextern-init on const selectany variables
In C, 'extern' is typically used to avoid tentative definitions when
declaring variables in headers, but adding an intializer makes it a
defintion. This is somewhat confusing, so GCC and Clang both warn on it.
In C++, 'extern' is often used to give implictly static 'const'
variables external linkage, so don't warn in that case. If selectany is
present, this might be header code intended for C and C++ inclusion, so
apply the C++ rules.

rL277342 made RecursiveASTVisitor visit lambda capture initialization
expressions (these are the Exprs in LambdaExpr::capture_inits()).
jdennett identified two issues with rL277342 (see comments there for details):
- It visits initialization expressions for implicit lambda captures, even if
shouldVisitImplicitCode() returns false.
- It visits initialization expressions for init captures twice (because these
were already traveresed in TraverseLambdaCapture() before rL277342)
This patch fixes these issues and moves the code for traversing initialization
expressions into TraverseLambdaCapture().
This patch also makes two changes required for the tests:
- It adds Lang_CXX14 to the Language enum in TestVisitor.
- It adds a parameter to ExpectedLocationVisitor::ExpectMatch() that specifies
the number of times a match is expected to be seen.

If possible, set the stack rlimit to at least 8MiB on cc1 startup, and work
around a Linux kernel bug where the actual amount of available stack may be a
*lot* lower than the rlimit.
GCC also sets a higher stack rlimit on startup, but it goes all the way to
64MiB. We can increase this limit if it proves necessary.
The kernel bug is as follows: Linux kernels prior to version 4.1 may choose to
map the process's heap as little as 128MiB before the process's stack for a PIE
binary, even in a 64-bit virtual address space. This means that allocating more
than 128MiB before you reach the process's stack high water mark can lead to
crashes, even if you don't recurse particularly deeply.
We work around the kernel bug by touching a page deep within the stack (after
ensuring that we know how big it is), to preallocate virtual address space for
the stack so that the kernel doesn't allow the brk() area to wander into it,
when building clang as a Linux PIE binary.

The patch also includes a fix for bootstrap dependencies so that the instrumented LTO tools don't get used when building the final stage, and it adds distribution targets to the passthrough.

Emit debug info for dynamic classes if they are imported from a DLL.
With -debug-info-kind=limited, we omit debug info for dynamic classes that live in other TUs. This reduces duplicate type information. When statically linked, the type information comes together. But if your binary has a class derived from a base in a DLL, the base class info is not available to the debugger.
The decision is made in shouldOmitDefinition (CGDebugInfo.cpp). Per a suggestion from rnk, I've tweaked the decision so that we do include definitions for classes marked as DLL imports. This should be a relatively small number of classes, so we don't pay a large price for duplication of the type info, yet it should cover most cases on Windows.
Essentially this makes debug info for DLLs independent, but we still assume that all TUs within the same DLL will be consistently built with (or without) debug info and the debugger will be able to search across the debug info within that scope to resolve any declarations into definitions, etc.

[CUDA] Raise an error if a wrong-side call is codegen'ed.
Summary:
Some function calls in CUDA are allowed to appear in
semantically-correct programs but are an error if they're ever
codegen'ed. Specifically, a host+device function may call a host
function, but it's an error if such a function is ever codegen'ed in
device mode (and vice versa).
Previously, clang made no attempt to catch these errors. For the most
part, they would be caught by ptxas, and reported as "call to unknown
function 'foo'".
Now we catch these errors and report them the same as we report other
illegal calls (e.g. a call from a host function to a device function).
This has a small change in error-message behavior for calls that were
previously disallowed (e.g. calls from a host to a device function).
Previously, we'd catch disallowed calls fairly early, before doing
additional semantic checking e.g. of the call's arguments. Now we catch
these illegal calls at the very end of our semantic checks, so we'll
only emit a "illegal CUDA call" error if the call is otherwise
well-formed.

Reapply [VFS] Skip non existent files from the VFS tree
Reapply r278457 with test fixed to not abouse fs case sensitivity.
When the VFS uses a YAML file, the real file path for a
virtual file is described in the "external-contents" field. Example:
...
{
'type': 'file',
'name': 'a.h',
'external-contents': '/a/b/c/a.h'
}
Currently, when parsing umbrella directories, we use
vfs::recursive_directory_iterator to gather the header files to generate the
equivalent modules for. If the external contents for a header does not exist,
we currently are unable to build a module, since the VFS
vfs::recursive_directory_iterator will fail when it finds an entry without a
reliable real path.
Since the YAML file could be prepared ahead of time and shared among
different compiler invocations, an entry might not yet have a reliable
path in 'external-contents', breaking the iteration.
Give the VFS the capability to skip such entries whenever
'ignore-non-existent-contents' property is set in the YAML file.

CodeGen: Replace ThinLTO backend implementation with a client of LTO/Resolution.
Summary:
This changes clang to use the llvm::lto::thinBackend function instead of

[Driver] Set the default driver mode based on the executable.
Currently, if --driver-mode is not passed at all, it will default
to GCC style driver. This is never an issue for clang because
it manually constructs a --driver-mode option and passes it.
However, we should still try to do as good as we can even if no
--driver-mode is passed. LibTooling, for example, does not pass
a --driver-mode option and while it could, it seems like we should
still fallback to the best possible default we can.
This is one of two steps necessary to get clang-tidy working on Windows.

This patch implements PR#22821.
Taking the address of a packed member is dangerous since the reduced
alignment of the pointee is lost. This can lead to memory alignment
faults in some architectures if the pointer value is dereferenced.
This change adds a new warning to clang emitted when taking the address
of a packed member. A packed member is either a field/data member
declared as attribute((packed)) or belonging to a struct/class
declared as such. The associated flag is -Waddress-of-packed-member.
Conversions (either implicit or via a valid casting) to pointer types
with lower or equal alignment requirements (e.g. void* or char*)
will silence the warning.

[Sema] Fix a crash on variadic enable_if functions.
Currently, when trying to evaluate an enable_if condition, we try to
evaluate all arguments a user passes to a function. Given that we can't
use variadic arguments from said condition anyway, not converting them
is a reasonable thing to do. So, this patch makes us ignore any varargs
when attempting to check an enable_if condition.
We'd crash because, in order to convert an argument, we need its
ParmVarDecl. Variadic arguments don't have ParmVarDecls.
