d7beeea228 Handle use side of __objc_exception__ attribute; when using an 
exception with this attribute we don't need to emit a weak definition
for the exception type information.

15894b791b 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.

dcceee734c Fix a couple of cases where Constant* pointers can dangle in 
ObjCNonFragileABITypesHelper by converting them to dynamic
getters.  This fixes a crash on rdar://6757213.  The others
should be converted over as well.

3088a31e96 remove ASTContext::buildObjCInterfaceType, which breaks canonical 
types.  It is no longer needed now that the code generator 
re-lays-out interfaces if they are defines after being laid out
from a forward decl.

66afeb5968 Some "prep" work for handling ObjC @-string constants that contain UTF-8. No functionality change. 
Changed GenerateConstantString() to take an ObjCStringLiteral (instead of a std::string). While this isn't strictly necessary, it seems cleaner and allows us to cache to "containsNonAscii" if necessary (to avoid checking in both Sema and CodeGen).

a374b68b5a Back out the patch in r66302, and re-fix it properly. We assume for 
performance that the type of the returned llvm::Value for an expression 
matches the converted type of the clang::Expr; mismatches will cause all
sorts of errors and silent miscompilations.

76b7acc49f First cut at zero-cost EH support. 
- Still manually generates the EH code; the parts related to cleanup
   need to be integrated into the cleanup stack (for proper
   interaction with VLAs, etc.).

 - Some differences vs gcc in corner cases; I believe our behavior is
   correct but need to verify/file bugs vs gcc.
