David Guillen Fandos 883f07f487 Fix small buf and add cheat error messages 
Some minor formating too

David Guillen Fandos 4fd456e158 Adding Code Breaker cheat support 
This works on both interpreter and dynarec.
Tested in MIPS, ARM and x86, still needs some more testing, some edge
cases can be buggy.

David Guillen Fandos d83f8fbd25 Fix Vita port and likely some Linux/Android hidden issues 
Using an invalid SP makes Vita crash (for an unkown reason) and makes
things like C signal handlers crash (luckily Retroarch doesn't use
them). It is also a violation of the ABI and not a great idea.
Recycled some little used registers to free SP. Perf should be roughly
the same.

David Guillen Fandos 34e672ed25 Simplify open load handling for MIPS and fix other arches 
Also rewrite a bit memory handlers for smaller functions.

David Guillen Fandos 7bebd3051c Remove dead code 
Turns out this was not even used! No need to fix it then!

David Guillen Fandos 8d52e613c7 Minor cleanup in ARM and MIPS 
Fix some small issues, mainly associated with undefined behaviour

David Guillen Fandos 2c6026cfe5 Move r15 to reg_a0 (instead of reg_mem) 
I think this does not make a difference at all in the code, since PC is
treated in a special way anyway (reloaded with an immediate when read
and treated as an indirect branch when written). However for the sake of
completeness I'm undoing what I did. (The comma fix stays :P)

David Guillen Fandos 7aaa280b9f Fix ARM dynarec 
Turns out there were a couple of very interesting and hard to track
bugs. A missing comma made the reg list too short, leaving the 31th
element at the mercy of the linker ordering algorithm, which seems to
work in some cases depending on the compiler version.
Also the cache flush code seemed not to work on my machine (OGA),
not sure why it wored in the past :/
