Recommit "Reorder (shl (add/sub (shl x, C0), y), C1) -> (add/sub (shl x, C0 + C1), (shl y, C1))" 2nd Try
First time caused build failure:
https://lab.llvm.org/buildbot/#/builders/183/builds/10447
but after investigating it seems to be unrelated. The same
test/build passed later with the original commit here:
https://lab.llvm.org/buildbot/#/builders/183/builds/10448
This is just expanding the existing pattern that exists for AND/XOR/OR
and gets a bit more parallelism in from the instruction sequence.
