[multiversion] Update Clang for the API change in LLVM r227731.
This moves all of the PassManager <-> Target communication to use the
new pass manager's TargetIRAnalysis even with the old pass manager. See
the LLVM commit for some of why things are moving in this direction, but
the short version is that this will enable us to create per-function
TargetTransformInfo objects that have correct subtarget information for
that function.

[X86] Rename _mm512_valign_epi64/32 intrinsics to _mm512_alignr_epi64/32 to match Intel docs. Make immediate argument to them an ICE. Fix mask size for the alignd version.
Create a new TargetCodeGenInfo for Windows on ARM to permit annotating the
functions with stack-probe-size (for /Gs and -mstack-probe-support) for
generating the stack probe necessary for Windows targets. This will be used by
the backend when lowering the frame to generate the stack probe appropriately.

Follow-up to r217302 and r227555: Don't crash on inline ~A::A() if A is an int.
Even with r227555, this still crashed:
struct S {
int A;
~A::A() {}
};
That's because ParseOptionalCXXScopeSpecifier()'s call to
ActOnCXXNestedNameSpecifier() doesn't mark the scope spec as invalid if sema
thought it's a good idea to fixit-correct "::" to ":". For the diagnostic
improvement done in r217302, we never want :: to be interpreted as :, so fix
this by setting ColonSacred to false temporarily.

Fix OpenCL 1.2 double as an optional core feature behaviour
In OpenCL 1.2, using double no longer requires using the pragma cl_khr_fp64,
instead a kernel is allowed to use double, but must first have queried
clGetDeviceInfo's CL_DEVICE_DOUBLE_FP_CONFIG.
Page 197, section 6.1.1 of the OpenCL 1.2 specification has a footnote 23
describing this behaviour.
I've also added test cases such that the pragma must be used if targeting
OpenCL 1.0 or 1.1, but is ignored in 1.2 and 2.0.

MS ABI: Implement proper support for setjmp
On targets which use the MSVCRT, setjmp is a macro which expands to
_setjmp or _setjmpex.
_setjmp and _setjmpex have a secret, hidden argument which is not listed
in the function prototype on X64 and WoA. This hidden argument always
seems to be the frame pointer.
_setjmpex isn't used on X86, _setjmp is magically replaced with a call
to _setjmp3. The second argument is zero for 'normal' setjmp/longjmp
pairs, otherwise it is a count of additional variadic arguments. This
is used when setjmp appears inside of a try or __try.
It is not safe to use a pointer to setjmp because _setjmp, _setjmpex and
_setmp3 are not compatible with setjmp.
For the --be8 flag, check explicitly for pre-v7 / pre-v6m cores.
Those used the old Big Endian support on ARM and don't need flags.
Refactor the logic in a separate common function, which also looks at
-march. Add corresponding logic for the Linux toolchain.

Revert a change from r222797 that is no longer needed and can cause
infinite recursion.
Also guard against said infinite recursion by adding an assert that will
trigger if CorrectDelayedTyposInExpr is called before a previous call to
CorrectDelayedTyposInExpr returns (i.e. if the TreeTransform run by
CorrectDelayedTyposInExpr calls a sequence of methods that
end up calling CorrectDelayedTyposInExpr, as the new test case had done
prior to this commit). Fixes PR22292.

DebugInfo: Attribute implicit boolean tests to the expression being tested, not to the outer use of that expression.
This is half a fix for a GDB test suite failure that expects to start at
'a' in the following code:
void func(int a)
if (a
&&
b)
...
But instead, without this change, the comparison was assigned to '&&'
(well, worse actually - because there was a chained 'a && b && c' and it
was assigned to the second '&&' because of a recursive application of
this bug) and then the load folded into the comparison so breaking on
the function started at '&&' instead of 'a'.
The other part of this needs to be fixed in LLVM where it's ignoring the
location of the icmp and instead using the location of the branch
instruction.
The fix to the conditional operator is actually a no-op currently,
because the conditional operator's location coincides with 'a' (the
start of the conditional expression) but should probably be '?' instead.
See the FIXME in the test case that mentions the ARCMigration tool
failures when I tried to make that change.

Avoid testing for a particular choice of resource dir.
Without this patch, this test was accidentally testing that
CLANG_RESOURCE_DIR, CLANG_LIBDIR_SUFFIX, and CLANG_VERSION_STRING
were set to a particular set of values.
The test was also getting pretty hairy since it was attempting to craft
a regular expression that covered "all" possible combinations of
settings for these configure-time constants.
Clean it up by directly capturing the resource directory in a FileCheck
variable.
The code building the code completion string for overloads was providing
less detail compared to the one building completion strings for function
declarations. There was no information about optionals and no information
about what's a parameter and what's a function identifier, everything
besides ResultType, CurrentParameter and special characters was classified
as Text.
This makes code completion strings for overload candidates to follow a
pattern very similar, but not identical, to the one in use for function
declarations:
- return type chunk: ResultType
- function identifier chunk: Text
- parameter chunks: Placeholder
- optional parameter chunks: Optional
- current parameter chunk: CurrentParameter

Use the real CXXScopeSpec when setting the correction SourceRange.
Otherwise, in the most important case and the only case where SS and
TempSS are different (which is when the CXXScopeSpec should be dropped,
and TempSS is NULL) the wrong SourceRange will be used in the fixit for
the typo correction. Fixes the remaining issue in PR20626.

Fix a think-o in handling ambiguous corrections for a TypoExpr.
Under certain circumstances, the identifier mentioned in the diagnostic
won't match the intended correction even though the replacement
expression and the note pointing to the decl are both correct.
Basically, the TreeTransform assumes the TypoExpr's Consumer points to
the correct TypoCorrection, but the handling of typos that appear to be
ambiguous from the point of view of TransformTypoExpr would cause that
assumption to be violated by altering the Consumer's correction stream.
This fix allows the Consumer's correction stream to be reset to the
right TypoCorrection after successfully resolving the percieved ambiguity.
Included is a fix to suppress correcting the RHS of an assignment to the
LHS of that assignment for non-C++ code, to prevent a regression in
test/SemaObjC/provisional-ivar-lookup.m.
