buffer generated for the current translation unit. If they are
different, complain and then ignore the PCH file. This effectively
checks for all compilation options that somehow would affect
preprocessor state (-D, -U, -include, the dreaded -imacros, etc.).

When we do accept the PCH file, throw away the contents of the
predefines buffer rather than parsing them, since all of the results
of that parsing are already stored in the PCH file. This eliminates
the ugliness with the redefinition of __builtin_va_list, among other
things.

used to compile the PCH file. If they are not, we emit a diagnostic

A CodeTextRegion wraps two kinds of data: FunctionDecl* or SymbolRef. 
The latter comes from the symbolic function pointer that are generated from
function calls or input data.

improvement, source locations read from the PCH file will properly
resolve to the source files that were used to build the PCH file
itself.

Once we have the preprocessor state stored in the PCH file, source
locations that refer to macro instantiations that occur in the PCH
file should have the appropriate instantiation information.
