David Guillen Fandos 46cad2958a Move a few more registers to context
This gets rid of some more absolute addrs in the MIPS dynarec.
Tested on several platforms, we should be good.

David Guillen Fandos c86b9064df Move palettes around to simplify MIPS dynarec
Will move also OAM structures to gain a few cycles per load/store.
Loads can also be optimized for an extra instruction per access.

David Guillen Fandos 1e8097ac79 Improve and simplify dynarec JIT area.
Also fix a regression on VITA.
Use gcc/OS cache flushing routines for MIPS32 instead of synci

David Guillen Fandos 462f0e9784 Improve cache flush magic
Make it better and more generic. Add support for MIPS32 and fix the
messy PSP code.

David Guillen Fandos 56dc6ecb70 Remove libco
This removes libco and all the usages of it (+pthreads).
Rewired all dynarecs and interpreter to return after every frame so that
libretro can process events. This required to make dynarec re-entrant.

Dynarecs were updated to check for new frame on every update (IRQ, cycle
exhaustion, I/O write, etc). The performance impact of doing so should
be minimal (and definitely outweight the libco gains). While at it,
fixed small issues to get a bit more perf: arm dynarec was not idling
correctly, mips was using stack when not needed, etc.

Tested on PSP (mips), OGA (armv7), Linux (x86 and interpreter). Not
tested on Android though.

David Guillen Fandos 02e35339ee Fix a ghost bug with some games
Affects at least SM Adv 4 on PSP, which doesn't load at all.
I think the MIPS pipeline does not like invalidating the Icache and
using it immediately after (seems to read an old value sometimes?).
Rewired it to not do that and instead jump to the handler directly.
