wine sources.  This was happening because HighlightMacros was 
calling EnterMainFile multiple times on the same preprocessor
object and getting an assert due to the new #line stuff (the
file in question was bison output with #line directives).

The fix for this is to not reenter the file.  Instead, 
relex the tokens in raw mode, swizzle them a bit and repreprocess
the token stream.  An added bonus of this is that rewrite macros
will now hilight the macro definition as well as its uses.  Woo.

Add some boilerplate to the PTH file to prepare for the caching of stats for directories (and negative stats too).

by DeclContexts (always) rather than by statements. 

DeclContext currently goes out of its way to avoid destroying any
Decls that might be owned by a DeclGroupOwningRef. However, in an
error-recovery situation, a failure in a declaration statement can
cause all of the decls in a DeclGroupOwningRef to be destroyed after
they've already be added into the DeclContext. Hence, DeclContext is
left with already-destroyed declarations, and bad things happen. This
problem was causing failures that showed up as assertions on x86 Linux
in test/Parser/objc-forcollection-neg-2.m.

Currently only used for 128-bit integers.

Note that we can't use the fixed-width integer types for other integer 
modes without other changes because glibc headers redefines (u)int*_t 
and friends using the mode attribute.  For example, this means that uint64_t
has to be compatible with unsigned __attribute((mode(DI))), and 
uint64_t is currently defined to long long.  And I have a feeling we'll 
run into issues if we try to define uint64_t as something which isn't 
either long or long long.

This doesn't get the alignment right in most cases, including 
the 128-bit integer case; I'll file a PR shortly.  The gist of the issue 
is that the targets don't really expose the information necessary to 
figure out the alignment outside of the target description, so there's a 
non-trivial amount of work involved in getting it working right.  That 
said, the alignment used is conservative, so the only issue with the 
current implementation is ABI compatibility.

This makes it trivial to add some sort of "bitwidth" attribute to make 
arbitrary-width integers; I'll do that in a followup.

We could also use this for stuff like the following for compatibility 
with gcc, but I have a feeling it would be a better idea for clang to be 
consistent between C and C++ modes rather than follow gcc's example for 
C mode.
struct {unsigned long long x : 33;} x;
unsigned long long a(void) {return x.x+1;}

- Add 'EvalBind', which will be used by 'EvalStore' to pull much of the value binding logic out of GRTransferFuncs.
- Rename many cases of 'St' to 'state'.

only insert spaces between tokens if the code had them or if they 
are actually required to avoid pasting.  This reuses the same
logic as -E mode.

given name in a given scope is marked as "overloadable", every
function declaration and definition with that same name and in that
same scope needs to have the "overloadable" attribute. Essentially,
the "overloadable" attribute is not part of attribute merging, so it
must be specified even for redeclarations. This keeps users from
trying to be too sneaky for their own good:

  double sin(double) __attribute__((overloadable)); // too sneaky
  #include <math.h>

Previously, this would have made "sin" overloadable, and therefore
given it a mangled name. Now, we get an error inside math.h when we
see a (re)declaration of "sin" that doesn't have the "overloadable"
attribute.

ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

_GCC_LIMITS_H_ is defined, when __GNUC__ is defined.

Also, we need to stay away from possible conflicts with header guards.
We should use CLANG_ to prefix all header guards.

union subobject initialization before checking whether the next
initiailizer was actually a designated initializer. This led to
spurious "excess elements in union initializer" errors. Thanks to
rdivacky for reporting the bug!
