Stop abusing StringRef. Fixes the Windows build.

I've also removed the duplicate check for PARSED_ATTR since it seems
unnecessary, and would have made the code more complicated.

Revert predefined decl tracking.

r158085 added some logic to track predefined declarations.  The main reason we
had predefined declarations in the input was because the __builtin_va_list
declarations were injected into the preprocessor input.  As of r158592 we 
explicitly build the __builtin_va_list declarations.  Therefore the predefined
decl tracking is no longer needed.

Revert r158700 and dependent patches r158716, r158717, and r158731.

The original r158700 caused crashes in the gcc test suite,
g++.abi/vtable3a.C among others. It also caused failures in the libc++
test suite.
