Asserting test case
Looks like rev 219900 broke generating debug info for typedef'd template types.
Attached is a reduced test case out of skia (gpu/gl/GrGLNameAllocator.cpp). The
test case works fine without the typedef, but asserts with the typedef:
clang: /hdd/sjcrane/multicompiler/src/include/llvm/Support/Casting.h:237:
typename llvm::cast_retty<X, Y*>::ret_type llvm::cast(Y*) [with X =
clang::MemberPointerType; Y = const clang::Type; typename llvm::cast_retty<X,
Y*>::ret_type = const clang::MemberPointerType*]: As
sertion `isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
