Review: http://llvm-reviews.chandlerc.com/D1546.

I have picked up this patch form Lawrence
(http://llvm-reviews.chandlerc.com/D1063) and did a few changes.

From the original change description (updated as appropriate):
This patch adds a check that ensures that modules only use modules they
have so declared. To this end, it adds a statement on intended module
use to the module.map grammar:

  use module-id

A module can then only use headers from other modules if it 'uses' them.
This enforcement is off by default, but may be turned on with the new
option -fmodules-decluse.

When enforcing the module semantics, we also need to consider a source
file part of a module. This is achieved with a compiler option

-fmodule-name=<module-id>.

The compiler at present only applies restrictions to the module directly
being built.

fix to come once I've tracked down the problem (which is pre-existing and not
related to the change which introduced this test).

literal operators. Also, for now, allow the proposed C++1y "il", "i", and "if"
suffixes too. (Will revert the latter if LWG decides not to go ahead with that
change after all.)

2. Some macros for clauses processing are replaced by private template methods.
3. Additional checks in sema analysis of OpenMP clauses.

gcc doesn't support "gcc -m sse" and this was not tested in clang and only
used for link argument on darwin, so this was very likely just a bug.

This solves two problems:

1) MSBuild will not flag the build as unsuccessful just because we print
   an error in the output, since "error(clang):" doesn't seem to match
   the regex it's using.

2) It becomes more clear that the diagnostic is coming from clang as
   supposed to cl.exe.

This doesn't change a lot since clang still thinks it knows all of the
-f*, -m* and -W* options for example.

Other than the options clang explicitly claims to know, this fixes pr9701.

if it changes.

Summary:
We enable ASAN's use-after-return instrumentation at compile-time,
but still keep it disabled at run-time.
This enables the users to flip the flag at run-time using environment variable
ASAN_OPTIONS=detect_stack_use_after_return=1 instead of using a separate build.
If UAR detection is disabled at run-time, this extra compile-time instrumentation
costs very small slowdown. On SPEC 2006 14 tests are not affected at all,
4 tests get ~ 1% slowdown and 453.povray gets 4%.
