I'm pretty sure you can do this already: you can recurse into a type
to find typedefs, getTypeSpecStartLoc returns the start of the
declaration specifiers, and you can re-lex the source and figure out
the precise location of the typedef name from there. It might be nice
to provide utility methods to do this, but I don't see any need for
any core changes.
Also, your suggestion doesn't really address where exactly you plan to
store your flag; there aren't any spare bits in QualType.
