cmd/compile: fix load-combining rules CL 33632 reorders args of commutative ops in order to make CSE for commutative ops more robust. Unfortunately, that broke the load-combining rules which depend on a certain ordering of OR ops' arguments. Introduce some additional rules that order OR ops' arguments consistently so that the load-combining rules fire. Note: there's also something else wrong with the s390x rules. I've filed #19059 for that. Fixes #18946 Change-Id: I0a5447196bd88a55ccee683c69a57b943a9972e1 Reviewed-on: https://go-review.googlesource.com/36911 Run-TryBot: Keith Randall <khr@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Josh Bleecher Snyder <josharian@gmail.com>
