PR18322. This test will be reenabled when the SDK gets fixed. In the meantime,
it is pretty disruptive to have this test keep failing.

The part that checks that certain functions are marked deprecated doesn't
seem that useful, and it has the bad effect that the test hard-coded the
locations of the notes from that test.

This ports the last Sema tests over to use the frontend directly, and adds a
local lit substitution to disable inappropriate %clang usage under this

Fixes <rdar://problem/15584219> and <rdar://problem/12241361>.
This change looks large, but all it does is reuse and consolidate
the delayed diagnostic logic for deprecation warnings with unavailability
warnings. By doing so, it showed various inconsistencies between the
diagnostics, which were close, but not consistent. It also revealed
some missing "note:"'s in the deprecated diagnostics that were showing
up in the unavailable diagnostics, etc.
This change also changes the wording of the core deprecation diagnostics.
Instead of saying "function has been explicitly marked deprecated"
we now saw "'X' has been been explicitly marked deprecated". It
turns out providing a bit more context is useful, and often we
got the actual term wrong or it was not very precise
(e.g., "function" instead of "destructor"). By just saying the name
of the thing that is deprecated/deleted/unavailable we define
this issue away. This diagnostic can likely be further wordsmithed
to be shorter.

Summary:
These are deprecated in VS 2012 according to MSDN. They don't actually
compile down to any code. They prevent the compiler from reordering
memory accesses across the barrier, which is what a memory-clobbering
volatile asm does.

is no need to go through the driver indirection here, and it clutters
things up as dependencies can sneak in for specific things the driver is
doing.

We already reject flags that don't have the CC1Option flag,
but we would previously do so after parsing the command-line
arguments.
Since the option parser now has a parameter for excluding options,
we should just use that instead.

This adds a test to make sure we define _WCHAR_T_DEFINED and
_NATIVE_WCHAR_T_DEFINED correctly in the preprocessor, and updates
stddef.h to set it when typedeffing wchar_t.

- We shouldn't even try to include stdint.h in hosted mode, as the dependency
on even parsing a platforms stdint.h might fail for some targets.

implementation of C99's attempt to control the C++ standard. *sigh*
The C99 standard says that certain macros in <stdint.h>, such as SIZE_MAX,
should not be defined when the header is included in C++ mode, unless
__STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS are defined. The C++11 standard
says "Thanks, but no thanks" and C11 removed this rule, but various C library
implementations (such as glibc) follow C99 anyway.
g++ prior to 4.8 worked around the C99 / glibc behavior by defining
__STDC_*_MACROS in <cstdint>, which was incorrect, because <stdint.h> is
supposed to provide these macros too. g++ 4.8 works around it by defining
__STDC_*_MACROS in its builtin <stdint.h> header.
This change makes Clang act like g++ 4.8 in this regard: our <stdint.h> now
countermands any attempt by the C library to implement the undesired C99 rules,
by defining the __STDC_*_MACROS first. Unlike g++, we do this even in C++98
mode, since that was the intent of the C++ committee, matches the behavior
required in C11, and matches our built-in implementation of <stdint.h>.

being included in C++. Don't define alignof or alignas in this case. Note that
the C++11 standard is broken in various ways here (it refers to the contents
of <stdalign.h> in C99, where that header did not exist, and doesn't mention
the alignas macro at all), but we do our best to do what it intended.

Xcode-style clang builds only support Xcode's architectures, so mips
isn't available and the driver tries to use gcc instead. cc1 will go
ahead and do -fsyntax-only for any platform it knows about even if it
can't actually compile.
llvm-svn: 164742
This also adds a definition for uint64_t, which was causing build failures
on some platforms. (I'm actually surprised this didn't happen on more
builders, but maybe the search paths are different.)

After discussion with several people, including Doug Gregor, we've

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.

Passing -verify to clang without -cc1 or -Xclang silently passes (with a
printed warning, but lit doesn't care about that). This change adds -cc1 or,
as is necessary in one case, -Xclang to fix this so that these tests are
actually verifying as intended.
I'd like to change the driver so this kind of mistake could not be made, but
I'm not entirely sure how. Further, since the driver only warns about unknown
flags in general, we could have similar bugs with a misspellings of arguments
that would be nice to find.
