Thanks for the pointer.
If I understand it correctly, the objection is not so much to the
macro, but to spreading the use of TM in IR passes.
Andrew, given what GlobalMerge is doing, do you think it should be
rewritten to use TTI?
The macro would still be used in AtomicExpandLoadLinkedPass and
CodeGenPrepare. IMHO it actually makes it easier to spot the llvm
passes that are using TM.
