Fix tests in order for them to not fail after r252604. Some expected attributes appear to be incorrect after optimizations are run and llvm will strip them. Use -O0 so that llvm will not have a chance to remove them. llvm-svn: 253458

Objective-C IRGen. Fix up the hueristics for determining if an ivar offset load is invariant iff inside an instance method and ivar belongs to instance method's class and one of its super class. // rdar://16095748 llvm-svn: 202872

[CodeGenObjC] Use a constant value for non-fragile ivar offsets when possible If a class inherits from NSObject and has an implementation, then we can assume that ivar offsets won't need to be updated by the runtime. This allows us to index into the object using a constant value and avoid loading from the ivar offset variable. This patch was adapted from one written by Pete Cooper. rdar://problem/10132568 Differential revision: https://reviews.llvm.org/D56802 llvm-svn: 351461
