Add tests on how clang currently handles some unknown options.

This is not to say this is the desired behavior, but it makes sure we notice
if it changes.

Add _mm_stream_si64 intrinsic.

While I'm here, also fix the alignment computation for the whole family of
intrinsics.

Fix argument types of some AVX2 intrinsics.

This fix makes our headers consistent with gcc.

Produce errors for unknown options.

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.

clang-cl: print diagnostics as "error(clang): foo" in /fallback mode

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.

Remove unused option.

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.

Handle standard libraries that miss out the space when defining the standard
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.)

Hopefully unbreak bots which are seeing an assert in this test. Temporary, real
fix to come once I've tracked down the problem (which is pre-existing and not
related to the change which introduced this test).

Module use declarations (II)

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.

Add -fmodule-map-file option.

With this option, arbitrarily named module map files can be specified
to be loaded as required for headers in the respective (sub)directories.

This, together with the extern module declaration allows for specifying
module maps in a modular fashion without the need for files called
"module.map".

Among other things, this allows a directory to contain two modules that
are completely independent of one another.
