cmd/compile: redo flag constant ops for arm
Encode the flag results in an auxint field instead of having
one opcode per flag state. This helps us handle the new *noov
branches in a unified manner.
This is only for arm, arm64 is in a subsequent CL.
We could extend to other architectures as well, athough it would
only be cleanup, no behavioral change.
Update #39505
