Slava Pestov beec309c9d AST: Fix debug info mangling of opaque result types with @_originallyDefinedIn ...

If a function's parameter or return types involve nominal types that
have been moved across modules using @_originallyDefinedIn, we must
take care to always mangle the opaque result type's name using the
original module names and not the current module names.

This was a problem with DWARF mangling, which normally disables
@_originallyDefinedIn for other purposes. Make sure to always
temporarily re-enable it when mangling an opaque result type.

Fixes rdar://problem/93822207.
