After discussion with several people, including Doug Gregor, we've
decided to change our approach here. If you have questions about this
header file, the commit removing it, etc., please reach out to me
off-list.

goodness because it provides opportunites to cleanup things. For example,
uint64_t t1(__m128i vA)
{
uint64_t Alo;
_mm_storel_epi64((__m128i*)&Alo, vA);
return Alo;
}
was generating
movq %xmm0, -8(%rbp)
movq -8(%rbp), %rax
and now generates
movd %xmm0, %rax

A test for this is checking if this compiles:
#include <float.h>
inline bool IsFinite(const double& number) {
return _finite(number) != 0;
}
That depends however on either mingw or msvc being installed, and
chapuni tells me there might be issues with float.h on mingw, so
no automated test is added.

appropriate modes.
Thanks to Aaron Ballman for working with me to figure out the initial
strategy here, and to Nico for reviewing and pestering me to actually
commit it.

From the Intel Optimization Reference Manual, Section 11.6.2. When data cannot
be aligned or alignment is not known, 16-byte memory accesses may provide better
performance.

match the behavior of GCC. Also add a test for these intrinsics, which
apparently have *zero* tests. =[ Not surprisingly, Clang crashed when
compiling these.
Fix the bug in CodeGen where we failed to bitcast the argument type to
x86mmx prior to calling the LLVM intrinsic. This fixes an assert on the
new 3dnow-builtins.c test.
This is one issue impacting the efforts to get Clang to emulate the
Microsoft intrinsics headers -- 3dnow intrinsics are implictitly made
available there.

into using non-absolute system includes (<foo>)...
... and introduce another hack that is simultaneously more heineous
and more effective. We whitelist Clang-supplied headers that augment
or override system headers (such as float.h, stdarg.h, and
tgmath.h). For these headers, Clang does not provide a module
mapping. Instead, a system-supplied module map can refer to these
headers in a system module, and Clang will look both in its own
include directory and wherever the system-supplied module map
suggests, then adds either or both headers. The end result is that
Clang-supplied headers get merged into the system-supplied module for
the C standard library.
As a drive-by, fix up a few dependencies in the _Builtin_instrinsics
module.

builds, and bring mm_alloc.h into the fold. Start playing some tricks
with these builtin modules to mirror the include_next tricks that the
headers already perform.

each of the targets. Use this for module requirements, so that we can
pin the availability of certain modules to certain target features,
e.g., provide a module for xmmintrin.h only when SSE support is
available.
Use these feature names to provide a nearly-complete module map for
Clang's built-in headers. Only mm_alloc.h and unwind.h are missing,
and those two are fairly specialized at the moment. Finishes
