Add platform independent AT91 JIT path to speed up SAM emulation

[toxieainc]

Maybe something like https://asmjit.com/ could help? That includes even Arm, and seems to be used by quite some multi-platform larger projects (e.g. GZDoom).

Also could aid potential SPIKE support at some point.

Is there some issue that tracks what needs to be done for SPIKE emulation? Linking to research / findings / ...

Sure, easy: emulate a complete PC running some Linux offspring.
Actually I guess it's easier to emulate the i486 platform running Pinball 2000 (SWEP1 / RFM).
And one of the first obstacles to overcome is a reliable microsecond timer.

Pin2K was done by erikie for MAME, so we 'just' would need to port all of this, including the MediaGX parts, etc. ;)
For SPIKE we may already be in the land of 'too much effort', true, and some other project like qemu might be better suited to be leveraged.
erikie went for the same with Pin2K in the end.

Nevertheless, replacing the existing AT91 JIT code may still be worth it, especially on mobile platforms.
