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
