[X86] Add 'sahf' CPU feature to frontend
Summary:
Make clang accept `-msahf` (and `-mno-sahf`) flags to activate the
`+sahf` feature for the backend, for bug 36028 (Incorrect use of
pushf/popf enables/disables interrupts on amd64 kernels). This was
originally submitted in bug 36037 by Jonathan Looney
<jonlooney@gmail.com>.
As described there, GCC also uses `-msahf` for this feature, and the
backend already recognizes the `+sahf` feature. All that is needed is to
teach clang to pass this on to the backend.
The mapping of feature support onto CPUs may not be complete; rather, it
was chosen to match LLVM's idea of which CPUs support this feature (see
lib/Target/X86/X86.td).
I also updated the affected test case (CodeGen/attr-target-x86.c) to
match the emitted output.

An implementation of the behavior described in `[dcl.fct.def.coroutine]/7`:
when a promise type overloads `operator new` using a "placement new"
that takes the same argument types as the coroutine function, that
overload is used when allocating the coroutine frame.
Simply passing references to the coroutine function parameters directly
to `operator new` results in invariant violations in LLVM's coroutine
splitting pass, so this implementation modifies Clang codegen to

[Sema] Toggle diags when finding allocators (NFCI)
Summary:
Many methods in Sema take a `bool Diagnose` parameter. Examples of such
methods include `Sema::FindDeallocationFunction` and
`Sema::SpecialMemberIsTrivial`. Calling these methods with
`Diagnose = false` allows callers to, for instance, check for the
existence of a deallocation function, without that check resulting in
error diagnostics being emitted if no matching deallocation function exists.
Add a similar `bool Diagnose` to the `Sema::FindAllocationFunctions`
method, so that checks for the existence of allocation functions can be
made without triggering error diagnostics.
This allows `SemaCoroutine.cpp`, in its implementation of the
Coroutines TS, to check for the existence of a particular `operator new`
overload, but then without error fall back to a default `operator new`
if no matching overload exists.

Clang first does codegen for block expression in the first line and deletes its block info.
Clang then tries to do codegen for the same block expression again for the second line,

The fix is to do normal codegen for both lines. Introduce an API to OpenCL runtime to
record llvm block invoke function and llvm block literal emitted for each AST block
expression, and use the recorded information for generating the wrapper kernel.
The EmitBlockLiteral APIs are cleaned up to minimize changes to the normal codegen

Another minor issue is that some clean up AST expression is generated for block

[analyzer] Inline constructors for destroyable temporaries.
Since r325210, in cfg-temporary-dtors mode, we can rely on the CFG to tell us
that we're indeed constructing a temporary, so we can trivially construct a
temporary region and inline the constructor.
Much like r325202, this is only done under the off-by-default
cfg-temporary-dtors flag because the temporary destructor, even if available,
will not be inlined and won't have the correct object value (target region).
Unless this is fixed, it is quite unsafe to inline the constructor.
If the temporary is lifetime-extended, the destructor would be an automatic
destructor, which would be evaluated with a "correct" target region - modulo
the series of incorrect relocations performed during the lifetime extension.
It means that at least, values within the object are guaranteed to be properly
escaped or invalidated.

[CFG] Provide construction contexts for temproary objects.
Constructors of C++ temporary objects that have destructors now can be queried
to discover that they're indeed constructing temporary objects.
The respective CXXBindTemporaryExpr, which is also repsonsible for destroying
the temporary at the end of full-expression, is now available at the
construction site in the CFG. This is all the context we need to provide for
temporary objects that are not lifetime extended. For lifetime-extended
temporaries, more context is necessary.

[analyzer] Decide on inlining destructors via EvalCallOptions.
EvalCallOptions were introduced in r324018 for allowing various parts of
ExprEngine to notify the inlining mechanism, while preparing for evaluating a
function call, of possible difficulties with evaluating the call that they
foresee. Then mayInlineCall() would still be a single place for making the
decision.
Use that mechanism for destructors as well - pass the necessary flags from the
CFG-element-specific destructor handlers.
Part of this patch accidentally leaked into r324018, which led into a change in
tests; this change is reverted now, because even though the change looked
correct, the underlying behavior wasn't. Both of these commits were not intended
to introduce any function changes otherwise.

[analyzer] Allow inlining constructors into return values.
This only affects the cfg-temporary-dtors mode - in this mode we begin inlining
constructors that are constructing function return values. These constructors
have a correct construction context since r324952.
Because temporary destructors are not only never inlined, but also don't have
the correct target region yet, this change is not entirely safe. But this
will be fixed in the subsequent commits, while this stays off behind the
cfg-temporary-dtors flag.
Lifetime extension for return values is still not modeled correctly.

[OpenMP] Fix trailing space when printing pragmas, by Joel. E. Denny
Summary:
-ast-print prints omp pragmas with a trailing space. While this
behavior is likely of little concern to most users, surely it's
unintentional, and it's annoying for some source-level work I'm
pursuing. This patch focuses on omp pragmas, but it also fixes
init_seg and loop hint pragmas because they share implementation.
The testing strategy here is to add usually just one '{{$}}' per
relevant -ast-print test file. This seems to achieve good code
coverage. However, this strategy is probably easy to forget as the
tests evolve. That's probably fine as this fix is far from critical.
The main goal of the testing is to aid the initial review.
This patch also adds a fixme for "#pragma unroll", which prints as
"#pragma unroll (enable)", which is invalid syntax.

[libclang] Add `CXSymbolRole role` to CXIdxEntityRefInfo
Summary:
CXIdxEntityRefInfo contains the member `CXIdxEntityRefKind kind;` to
differentiate implicit and direct calls. However, there are more roles
defined in SymbolRole. Among them, `Read/Write` are probably the most
useful ones as they can be used to differentiate Read/Write occurrences
of a symbol for document highlight in a text document.

[Sema] Don't mark plain MS enums as fixed
Summary:
This fixes a flaw in our AST: PR27098
MSVC always gives plain enums the underlying type 'int'. Clang does this
as well, but we claim the enum is "fixed", as if the user actually wrote
': int'. It means we end up emitting spurious -Wsign-compare warnings on
code like this:
enum Vals { E1, E2, E3 };
bool f(unsigned v1, Vals v2) {
return v1 == v2;
}
We think 'v2' can take on negative values because we think 'Vals' is
fixed. This fixes that.

Make attribute-target on a Definition-after-use update the LLVM attributes
As reported here: https://bugs.llvm.org/show_bug.cgi?id=36301
The issue is that the 'use' causes the plain declaration to emit
the attributes to LLVM-IR. However, if the definition added it
later, these would silently disappear.
This commit extracts that logic to its own function in CodeGenModule,
and has the attribute-applications done during 'definition' update
the attributes properly.

ASan+operator new[]: Add an option for more thorough operator new[] cookie poisoning
Summary:
Right now clang is skipping array cookie poisoning for any operator
new[] which is not part of the set of replaceable global allocation
functions.
This commit adds a flag to tell clang to poison all operator new[]
cookies.
A previous review was poisoning all array cookies unconditionally, but
there is an edge case which would stop working under ASan (a custom
operator new[] saves whatever pointer it returned, and then accesses
it).
This newer revision adds a command line argument to toggle this feature.
