33bf3e758d Diagnose uninitialized uses of a variable within its own initializer. 
This is basically the same idea as the warning on uninitialized uses of
fields within an initializer list. As such, it is on by default and
under -Wuninitialized.

Original patch by Richard Trieu, with some massaging from me on the
wording and grouping of the diagnostics.

2f1e36bfd0 Rename tok::eom to tok::eod. 
The previous name was inaccurate as this token in fact appears at
the end of every preprocessing directive, not just macro definitions.
No functionality change, except for a diagnostic tweak.

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.

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.
