Log:
Avoid crash when dumping LocInfoType.

LocInfoType is a helper type used internally inside Sema and Parser, it
does not exist in valid AST. LocInfoType uses code value outside the
range of valid Type codes, as a result, dumping such type causes error.
The fix allows correct dumping LocInfoType.
