This variant didn't seem to make much difference either (see prev commit)

Add small ARM perf experiment. Did not help on ARMv7 so turned it off.
...
xsacha might want to try it on ARMv6.

armjit: Use a MOV for add/or with 0.
...
Might skip the ALU, so might be faster.

Also improve vcmp on ARM.

Add an optimization to discard registers at the end of functions when possible.
...
Works in some games but crashes many so hiding it for now. Do not add UI.

ARMv6: Fix offsets > 4096 for litpool. More aggressive check.
...
Somehow Scooby Doo gets to offsets of ~4200 unless i drop the threshold down to ~3200. Not sure why the offset can jump by so much in one instruction.
Makes Scooby Doo playable now instead of showing a blue screen in the main game. Likely affects other games.

It seems we're spending a decent amount of time there, which isn't
entirely unexpected. We can eliminate some things easily.
