338f9aaab2 Handle locations coming from macro instantiations properly in SourceManager::isBeforeInTranslationUnit(). 
Fixes rdar://8790245 and http://llvm.org/PR8821.

1cb0de1d4c Fix diagnostic pragmas. 
Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state.
Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect
a lot of places, like C++ inline methods, template instantiations, the lexer, etc.

Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.

Fixes rdar://8365684.

b19289331d This really seems like a boring set of fixes to our tests to make them more 
independent of the underlying system. Let me know if any of these are too
aggressive.

18a2c2c0b9 Split out -Wconversion warnings about constant precision into their 
own subcategory, -Wconstant-conversion, which is on by default.

Tweak the constant folder to give better results in the invalid
case of a negative shift amount.

Implements rdar://problem/6792488

2c8028bcf4 In ~Preprocessor(), also cleanup the MacroInfo objects left-over from stray "#pragma push_macro" uses. This

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.

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.

guard macro is already defined for the first occurrence of the
header.  If it is, the body will be skipped and not be properly
analyzed for the include guard optimization.
