Microsoft's Source Annotation Language (SAL) defines a bunch of keywords
for annotating the inputs and outputs of functions. Empty definitions
for the keywords are provided by <stdlib.h> -> <crtdefs.h> -> <sal.h>.
This makes it basically impossible to include MSVC's stdlib.h and
Clang's *mmintrin.h headers at the same time if they have variables
named __in. As a workaround, I've renamed those variables.
This fixes the Modules/compiler_builtins.m test which was XFAILed,
presumably due to this conflict.

While we're here, extend the module map to cover most of the
newly-added instrinsic headers. Only wmmintrin.h is missing, because
it needs to be split into AES/PCLMUL subheaders (as a separate commit).

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.

On Cygwin, at first, <stddef.h> is included without __need_wint_t.
Next, <stddef.h> is included with __need_wint_t, though Modules feature would not process <stddef.h> twice.
Then, wint_t is not found in system headers.

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

requirements; they'll be handled separately. Part of
