courbet@, I think this should produce at least as good compile time as https://reviews.llvm.org/D53289. Can you verify on your testcase? If so, I move we drop https://reviews.llvm.org/D53289 (and https://reviews.llvm.org/D31068) in favor of this.

----------------
Apparently FileCheck balks at dealing with this many too many deferred lines in a DAG match. This is just a noop reordering to be closer to the output asm.
