const char*'s are now not converted to std::strings when the diagnostic
is formed, we just hold onto their pointer and format as needed.

This commit makes DiagnosticClient::FormatDiagnostic even more of a 
mess, I'll fix it in the next commit.

__builtin_prefetch code to only emit one diagnostic per builtin_prefetch.
While this has nothing to do with the rest of the patch, the code seemed
like overkill when I was updating it.

not "int".

Fix a typo in the promotion of enumeration types that was causing some
integral promotions to look like integral conversions (leading to
extra ambiguities in overload resolution).

Check for "acceptable" overloaded operators based on the types of the
arguments. This is a somewhat odd check that is specified by the
standard, but I can't see why it actually matters: the overload
candidates it suppresses don't seem like they would ever be picked as
the best candidates.

 - Only focusing on llvm_gcc_c for now, eventually this needs to be
   refactored so it can be shared via all the gcc-like tools.

- Add variants of IsNonPragmaNonMacroLexer to accept an IncludeMacroStack entry
  (simplifies some uses).
- Use IsNonPragmaNonMacroLexer in Preprocessor::LookupFile.

Performance testing of -Eonly on Cocoa.h shows no performance regression because
of this patch.

to support operators defined as member functions, e.g.,

  struct X { 
    bool operator==(X&);
  };

Overloading with non-member operators is supported, and the special
rules for the implicit object parameter (e.g., the ability for a
non-const *this to bind to an rvalue) are implemented.

This change also refactors and generalizes the code for adding
overload candidates for overloaded operator calls (C++ [over.match.expr]),
both to match the rules more exactly (name lookup of non-member
operators actually ignores member operators) and to make this routine
more reusable for the other overloaded operators.

Testing for the initialization of the implicit object parameter is
very light. More tests will come when we get support for calling
member functions directly (e.g., o.m(a1, a2)).
