Michel Heily 28fb9ffa70 chore: Refactor into crates 
Been wanting to do this for a long time.
This does impose performance issues when building with the vanilla
release profile, as cargo does not perform optimizations across crate
boundary (we care mostly about inlining).
so I added release-lto profile

Also fixed some broken stuff I found across the project, meh

Michel Heily 20506091cc [perf] arm: Improve performance with barrel shifter. 
Instead of using a struct member to hold the last barrel shifter carry output, which is expansive as it needs to be saved/loaded from memory, I now pass the carry around as an INOUT parameter.
Using perf anotate really shows high perctile of samples being spent on reading/writing `self.bs_carry_out`

Since this is a rather "surgical" changeset, I have made sure to run it against eggvance test suite, mGBA test suite and some games as well.

I actually saw better improvements than what the benchmark measured, but 7% is decent enough :)

Michel Heily 21708a3d58 [perf] sysbus: Improve add_cycls() 
Fulfill TODO from long ago, I used perf-record (--call-graph dwarf)  and detected that add_cycles() was hot enough,
I added 2 optimizations:
- Removed bound checks from array accesses
- Increase the LUT size to include dummy entries for open-bus to eliminate the if check
