Handle `DISubroutineType` up-front rather than as part of a branch for `DICompositeTypeBase`. The only shared code path was looking through the base type, but `DISubroutineType` can never have a base type. This also removes the last use of `DICompositeTypeBase`, since we can strengthen the cast to `DICompositeType`. llvm-svn: 243159
