Fix missing location information for error reporting of TypeInfo in betterC

Browse source 
This fixes an issue where any instantiation of TypeInfo in the final
output would lead to a cryptic error with no file or line information.
This change brings ldc in line with dmd's reporting of the same error,
which at least gives file and line information to discover the problem.
