74e4694 moved ObjCARCContract from running before the codegen pipeline into addISelPrepare(), which runs after PreISelIntrinsicLowering. This broke ObjCARCContract's retainRV-to-claimRV optimization because ObjCARCContract identifies ARC calls via intrinsics, not their lowered counterparts. This patch restores the pre-74e4694 ordering by moving ObjCARCContract to addISelPasses. The IntrinsicInst.cpp change looks extraneous but is required here: ObjCARCContract may now rewrite the bundle operand from retainRV to claimRV. When PreISelIntrinsicLowering then encounters this new intrinsic use, lowerObjCCall asserts mayLowerToFunctionCall. Assisted-by: claude rdar://137997453
