Pete Cooper	be4f571107	Change the objc ARC optimizer to use the new objc.* intrinsics ... We're moving ARC optimisation and ARC emission in clang away from runtime methods and towards intrinsics. This is the part which actually uses the intrinsics in the ARC optimizer when both analyzing the existing calls and emitting new ones.

Shoaib Meenai	074728a2a9	[ObjCARC] Prevent code motion into a catchswitch ... A catchswitch must be the only non-phi instruction in its basic block; attempting to move a retain or release into a catchswitch basic block will result in invalid IR. Explicitly mark a CFG hazard in this case to prevent the code motion. Differential Revision: https://reviews.llvm.org/D46482 llvm-svn: 332430	2018-05-16 04:52:18 +00:00
