Now that LLVM is emitting version 2 of the AMD code object, we can
start using lld again for linking instead of our custom tool.

OpenMP 4.5 adds taskloop/taskloop simd directives. These directives
allow to use lastprivate clause. Patch adds codegen for this clause.

* an unscoped enumerator whose enumeration is a class member is itself a class

r217178 changed clang to add function attribute uwtable by default on
Win64, which caused the __eh_frame section to be emitted by default.
This commit restores the previous behavior for MachO targets.

these, the normal code to filter out non-visible names from name lookup results
does not apply.

This option, like the corresponding gcc option, is SystemZ-specific and
enables storing frame backchain links, as specified in the ABI.

The change from llvm::VariadicFunction to internal::VariadicFunction
broke the extraction of hasAnyName().
equalsNode was broken because the argument type is 'const XXXX*' and
the internal space caused a failure on the regex.

This fixes a crash that occurs when a block captures a reference that is
captured by its enclosing lambda.

BuildBlockForLambdaConversion.
Previously, clang would build an incorrect AST for the following code:
id test() {
return @{@"a": [](){}, @"b": [](){}};
}
ReturnStmt 0x10d080448
`-ExprWithCleanups 0x10d080428
|-cleanup Block 0x10d0801f0 // points to the second BlockDecl
...
-BlockDecl 0x10d07f150 // First block
...
-BlockDecl 0x10d0801f0 // Second block
...
`-ExprWithCleanups 0x10d0801d0
|-cleanup Block 0x10d07f150 // points to the first BlockDecl
To fix the bug, this commit enters a new evaluation context to reset
ExprNeedsCleanups before each block is parsed.

r268509 causes this test case to be fully unrolled, so checking for an icmp is
no longer valid. Given that this test is for ARC anyway, checking for the icmp seems
unecessary.

The issue happened when a macro contained a full for or
while statement, which body ended at the end of the macro.

Let the loop unroll pass handle /Os. It already checks that option and adjust its thresholds accordingly. Also, will allow the #pragma unroll to have an effect in /Os.

Summary: Matcher proposed in the review of checker misc-assign-operator (name pending). Its goal is to find the direct enclosing function declaration of a statement and run the inner matcher on it. Two version is attached in this patch (thus it will not compile), to be decided which approach to take. The second one always chooses one single parent while the first one does a depth-first search upwards (thus a height-first search) and returns the first positive match of the inner matcher (thus it always returns zero or one matches, not more). Further questions: is it enough to implement it in-place, or ASTMatchersInternals or maybe ASTMatchFinder should be involved?

This code implements builtin_setjmp and builtin_longjmp exception handling intrinsics for 32-bit Sparc back-ends.
The code started as a mash-up of the PowerPC and X86 versions, although there are sufficient differences to both that had to be made for Sparc handling.
Note: I have manual tests running. I'll work on a unit test and add that to the rest of this diff in the next day.
Also, this implementation is only for 32-bit Sparc. I haven't focussed on a 64-bit version, although I have left the code in a prepared state for implementing this, including detecting pointer size and comments indicating where I suspect there may be differences.

This commit fixes the IdentifierIterator to actually include identifiers
from a PCH or precompiled preamble when there is also a global module
index. This was causing code-completion (outside of C++) and
typo-correction to be missing global identifiers defined in the
PCH/preamble. Typo-correction has been broken since we first started
using the module index, whereas code-completion only started relying on
identifier iterator in r232793.

These constructs are only applicable to a debugger capable of loading a
Clang AST, so omit them for brevity when not doing so.
We could potentially propagate more of CodeGenOptions through the
ObjectFilePCGContainerOperations for consistency (so the next person who
adds some CodeGenOpts feature that tweaks debug info output doesn't get
caught by this), so I'm open to objections/alternatives there, but went
with this for now.
Tested just a couple of basic cases (one direct, one indirect (through
the ObjectFilePCHContainerOperations) & fixed up other cases to pass the
-debugger-tuning flag as appropriate.

Use a utility function to check whether the number of elements is a power of 2
and drop the redundant upper limit (a 128-bit vector with more than 16 elements
would have each element < 8 bits, not possible).

If we are devirtualizing, then we want to compute the 'this' adjustment
of the devirtualized target, not the adjustment of the base's method
definition, which is usually zero.

We were seeing an internal failure when running this test. I can't
see a good reason for the difference, but the simple fix is to use

r268261 made Clang "expand" more struct arguments on Windows. It removed
the check for 'RD->isCLike()', which was preventing us from attempting
to expand structs with reference type fields.
Our expansion code was attempting to load and pass each field of the
type in turn. We were accidentally doing one to many loads on reference
type fields.
On the function prologue side, we can use
EmitLValueForFieldInitialization, which obviously gets the address of
the field. On the call side, I tweaked EmitRValueForField directly,
since this is the only use of this method.

It isn't necessary to call hasDefaultArg because we can't rematerialize
