- Be explicit about opcodes when looking for a constant.
- Add fixme to see if we can canonicalize where the constant shows up at a point earlier than selection.
- Some other refactoring to make the function a bit clearer.

(The case where the constant is on the other side does come up a couple times in the MultiSource tests at -O3.)
