81f38c14be
integrate changes from ARM64 backend and more
...
- better handle LDM/STM in reg alloc
- unify Halted and IRQ in anticipation for branch inlining
- literal optimisations can be disabled in gui
- jit blocks follow simple returns
- fix idle loop detection
- break jit blocks on IRQ (fixes saving in Pokemon White)

fixes Dragon Quest IX
move code with side effects out of assert, fixes release build
(thanks to m4wx for this one)
also remove some leftovers of jit pipelining

new block cache and much more...
...
- more reliable code invalidation detection
- blocks aren't stopped at any branch, but are being followed
if possible to get larger blocks
- idle loop recognition
- optimised literal loads, load/store cycle counting
and loads/stores from constant addresses
