[Clang] Replace cc1 options '-mdisable-fp-elim' and '-momit-leaf-frame-pointer' with '-mframe-pointer' After D56351 and D64294, frame pointer handling is migrated to tri-state (all, non-leaf, none) in clang driver and on the function attribute. This patch makes the frame pointer handling cc1 option tri-state.

CodeGenObjCXX: handle inalloca appropriately for msgSend variant objc_msgSend_stret takes a hidden parameter for the returned structure's address for the construction. When the function signature is rewritten for the inalloca passing, the return type is no longer marked as indirect but rather inalloca stret. This enhances the test for the indirect return to check for that case as well. This fixes the incorrect return classification for Windows x86. llvm-svn: 326362
