Eric Fiselier 916223b61f [libcxx] Add --show-unsupported and --show-xfail to check-libcxx's default LIT args.
Summary:
In order to gather more information about testsuite results these flags should be added to LIT's default args.
These new switches were recently added to LIT. It been more than two weeks since both switches were added.
I think its time we add these to our LIT flags.

Richard Smith 234ff47366 [modules] Put class template declarations into the scope in which they're
declared, rather than putting them into the template parameter scope. We
previously had *no record* in the scope for class template declarations, once
those declarations completed and their template parameter scopes were popped.
This in turn caused us to be unable to merge class template declarations that
were declared in the global scope (where we use scope lookup rather than
DeclContext lookup for merging), when loading a module.

Rafael Espindola f7ecb11572 Add support for comdats to the gold plugin.
There are two parts to this. First, the plugin needs to tell gold the comdat by
setting comdat_key.

What gets things a bit more complicated is that gold only seems
symbols. In particular, if A is an alias to B, it only sees the symbols
A and B. It can then ask us to keep symbol A but drop symbol B. What
we have to do instead is to create an internal version of B and make A
an alias to that.

At some point some of this logic should be moved to lib/Linker so that
we don't map a Constant to an internal version just to have lib/Linker
map that again to the destination module.

The reason for implementing this in tools/gold for now is simplicity.
With it in place it should be possible to update clang to use comdats
for constructors and destructors on ELF without breaking the LTO
bootstrap. Once that is done I intend to come back and improve the
interface lib/Linker exposes.

This commit expands llvm-cov's functionality by adding support for a new code coverage
tool that uses LLVM's coverage mapping format and clang's instrumentation based profiling.
The gcov compatible tool can be invoked by supplying the 'gcov' command as the first argument,
or by modifying the tool's name to end with 'gcov'.

Fixes PR20425.

During slice building, if all of the incoming values of a PHI node are the same, replace the PHI node with the common value. This simplification makes alloca's used by PHI nodes easier to promote.

David Blaikie 8608466148 DebugInfo: Test that the loop backedge in a range-for is attribute to the loop header.
This already works, but somewhat by accident (due to the order of
emission in clang, the location is set to the loop header (during the
emission of the iteratior increment) before the loop backedge is
emitted), so let's just add a test for symmetry and future-proofing.

Similar to r215768 (which fixed the same case for while loops). To quote
r215768's commit message:

"A little test case simplification - this could be simplified further,
though there are certainly interesting connections to the if/else
construct so I'm hesitant to remove that entirely though it does appear
somewhat unrelated.

(similar fix to r215766, related to PR19864)"

There's no need to do this if the user doesn't call va_start. In the

parameters with musttail calls, and they won't need these spills for
handling va_start.

Most of the test suite changes are adding va_start calls to existing
tests to keep things working.

Reid Kleckner af5fd6a4d5 Fix PR17239 by changing the semantics of the RemainingArgsClass Option kind
This patch aims at fixing PR17239.

This bug happens because the /link (clang-cl.exe argument) is marked as
"consume all remaining arguments". However, when inside a response file,
/link should only consume all remaining arguments inside the response
file where it is located, not the entire command line after expansion.
The LLVM side of the patch will change the semantics of the
RemainingArgsClass kind to always consume only until the end of the
response file when the option originally came from a response file.
There are only two options in this class: dash dash (--) and /link.

This is the Clang side of the patch in http://reviews.llvm.org/D4899

This warning is basically useless because the "previous versions" being referred to is MSVC 2005 and earlier, and we obviously do not care about them. However, this warning isn't particularly chatty (I don't recall ever seeing it previously), and it has the opportunity to point out cases where the cv-qualifiers differ unintentionally (like this case), so I am leaving it enabled for now.
