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)

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

abandon pipelining on jit
...
fixes Golden Sun Dawn
this makes the cpu state incompatible between interpreter and JIT. That's why switching cpu mode requires a restart(not requiring is stupid anyway) and the pipeline is manually filled when making a save state.

3D: keep the rasterizer from accidentally going out of bounds when given very flat X-major edge slopes.
...
this, by a fucking shitshow of butterfly effect, ends up fixing #234 . technically, the rasterizer was going out of bounds, which, under certain circumstances, caused interpolation to shit itself and generate Z values that were out of range (but still ended up in the zbuffer). sometimes those values ended up negative, which caused these glitches when polygons had to be drawn over those.
about fucking time.
