[ms-cxxabi] Destroy temporary record arguments in the callee

Itanium destroys them in the caller at the end of the full expression,
but MSVC destroys them in the callee.  This is further complicated by
the need to emit EH-only destructor cleanups in the caller.

This should help clang compile MSVC's debug iterators more correctly.
There is still an outstanding issue in PR5064 of a memcpy emitted by the
LLVM backend, which is not correct for C++ records.

Fixes PR16226.

Disable an assertion death test when using MSVC's assert()

MSVC's debug runtime prints assertion failures in wide characters, which
gtest doesn't understand.

[Modules] If a module map resides in a system header directory, treat it as a system module.

This prevents -pedantic from causing warnings in the system headers
used to create modules. Fixes <rdar://problem/14201171>.

Revert "[analyzer] Handle zeroing CXXConstructExprs."

Per review from Anna, this really should have been two commits, and besides
it's causing problems on our internal buildbot. Reverting until these have
been worked out.

[NVPTX] Fix inline asm test case to use LLVM IR instead of PTX so it works even when the NVPTX target is not built

Check for trivial constructibility before emptiness in ARM ABI.

According to the Itanium ABI (3.1.1), types with non-trivial copy constructors
passed by value should be passed indirectly, with the caller creating a
temporary.

We got this mostly correct, but forgot that empty structs can have non-trivial
constructors too and passed them incorrectly. This simply reverses the order of
the check.

Teach ARM va_arg to ignore empty structs.

Empty structs are ignored for parameter passing purposes, but va_arg was
incrementing the pointer anyway which could lead to va_list getting out of
sync.
