Chandler Carruth 5ac1e8e6b1 Begin fixing Clang's predefined macros for various architectures. This 
is *very* much a WIP that I'll be refining over the next several
commits, but I need to get this checkpoint in place for sanity.

This also adds a much more comprehensive test for architecture macros,
which is roughly generated by inspecting the behavior of a trunk build
of GCC. It still requires some massaging, but eventually I'll even check
in the script that generates these so that others can use it to append
more tests for more architectures, etc.

Next up is a bunch of simplification of the Targets.cpp code, followed
by a lot more test cases once we can reject invalid architectures.

Douglas Gregor b63ab9477c Only predefine the __EXCEPTIONS macro if C++ exceptions are turned on. 
Only predefine the OBJC_ZEROCOST_EXCEPTIONS macro if Objective-C
exceptions are turned on. Fixes PR10910.

Francois Pichet 84133e41be Upgrade Microsoft's __int8, __int16, __int32 and __int64 types from builtin defines to real types. 
Otherwise statements like:
  __int64 var = __int64(0);

would be expanded to:
  long long var = long long(0);

and fail to compile.

Chris Lattner a09e8efd1f Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

Daniel Dunbar 120a1e9d0f Headers: Define __INT64_TYPE__ in terms of getInt64Type(), which isn't always 
'long'. The practical upshot is so that the uint64_t we define in our stdint.h
ends up being compatible with that defined by gcc (at least on Darwin), which
otherwise could lead to type incompatibilities with other system headers.

Daniel Dunbar 0def3d17cb ARM: Honor -mfpu= and set __VFP_FP__ and __ARM_NEON__ "correctly". 
- Correctly is in quotes, because we are following what I interpreted as GCC's
   intent (which diverges from practice, naturally).
 - Also, fix the arch define for arm1136jf-s.

Daniel Dunbar acde99ea52 ARM: Fix predefines (__ARM_ARCH_..., __REGISTER_PREFIX). 
- This should be done leveraging the backend, but I'm a little refactored
   out. I'll fix it one day, I promise.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. 
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Ken Dyck 9b25f781c5 Restore __INTMAX_TYPE__, __UINTMAX_TYPE__, __PTRDIFF_TYPE__, and 
__INTPTR_TYPE__ as the last is used in the test/CodeGen/const-init.c and all
could potentially be in use in the wild. My apologies.

__INTn_C_SUFFIX__ macros that are defined for types with corresponding
constant suffixes (i.e. long and long long).

Chris Lattner 55c9877b66 Generalize stdint.h for non-8-bit-multiple types, patch by 
Ken Dyck!

"This adds definitions for types of 8-bit multiples
from 8 to 64 to stdint.h and rationalizes the selection of types 
for the exact-width definitions in InitPreprocessor.cpp."

Chris Lattner 0fb5bbd401 do not store wchar/char16/char32/intmax width/alignment info 
into TargetInfo, just derive this based on the underlying type.
