Various fixes to symbols used for Obj-C x86_64 metadata.
- Changed method names to match gcc (categories names still aren't
mangled in).
- Expose correct name for class and metadata symbols (although
-fvisibility=hidden isn't yet correct).
- Remove several things from llvm.used that didn't need to be there
(I suspect this can still be trimmed).
- Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
needed).
- Hide EH type class info with -fvisibility=hidden
- Change setGlobal[Option]Visibility to not change the visibility of
functions with internal linkage.
