David Guillen Fandos eab44b9e0b Enable runtime dynarec enable/disable
Added a more thorough cache cleanup for reset/mode-change too.
Fixed the mmap initialization that ends up leaking memory.
Minor x86 asm fixes for Android.

David Guillen Fandos fb7ca09b01 Remove BIOS reserved translation area
This is not really necessary since it can share area with ROM.
Performance impact should be very minimal (haven't noticed it myself)
and could be compensated (even by a positive offset) if we bump the ROM
cache area size.
Tested with several dynarecs.

David Guillen Fandos 5ffd2832e8 Rewrite of the MIPS dynarec stubs
This allows us to emit the handlers directly in a more efficient manner.
At the same time it allows for an easy fix to emit PIC code, which is
necessary for libretro. This also enables more platform specific
optimizations and variations, perhaps even run-time multiplatform
support.

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 3d558413fd Fix x86 dynarec, broken by d10c4afe
The dynarec expects function args to be located in registers instead of
the stack, which is not the default calling convetion in GCC/clang.

Francisco José García García 6ab0992ecf (VITA) Dynarec WIP 2016-08-08 00:31:21 +02:00
aliaspider f1d14fbe7c (3ds) dynarec: map the translation caches to specific addresses at
runtime, increases compatibility with loaders that can reloacate each
program section seperately.
move the svc enabling functions to the frontend.

aliaspider 0c72336d44 (CTR/3DS) using a heap allocator with a size determined at runtime can
remove the static memory limitation, no need to use the smaller dynarec
buffer size.
