This may allow better flushing. Not sure if these are the best regs,

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.
