e0a60a40a5 Remove unused mojs array from ppcState. 
This was some unused array just sitting in our global ppcState struct.
I've got no idea what its use was /supposed/ to be used for if ever implemented.

2599cd545e JIT: make backpatch handle sign-extend from 8 bits correctly. 
I don't think this is actually possible to trigger at the moment... but
it matches the implementation of SafeLoadToReg.

336b55bbc4 BS2 emulation: set up a reasonable BAT during startup. 
It doesn't really matter much at the moment given our current terrible MMU
emulation, but it will start mattering once our MMU emulation gets more
accurate.

a9a2d3d98d New frsqrte implementation; verified accurate. 
This is similar to the old implementation, but it uses smaller tables, and
handles more edge cases correctly.  (hwtest coming soon.)

567724b2f8 Jit: get rid of incorrect implementations of fres and frsqrte. 
The existing implementations produce answers which aren't consistent with
the hardware, and games care about correct floating point math.

These can be reimplemented at some point in the future, if someone cares
enough, but the general case is probably too much code to inline.

(I'm leaving the ARM implementations in place by request, even though they
suffer the same issues.)

d08abfc14e JIT: JitBaseBlockCache::InvalidateICache no longer memsets iCache memory to INVALID_BYTE. 
This is redundant, since we reset the valid_block bits any way.
However, this was a source of a significant performance issues in some games.
In particular, Metal Gear Solid: Twin Snakes.

de1e2127dc JIT: JitBaseBlockCache::valid_block is now std::vector<bool>

cdec575bef Fixes games that use the MMU to page in code(Rogue Leader). 
The issue was that on memory exception we wouldn't call in to PPCAnalyst and our code_block would retain the previous blocks information.
This would cause us to compile the previous blocks instructions in prior to the exception exit.

727ef4a625 JIT: unify JitAsm for JIT64 and JIT64IL. 
Having a bunch of nearly identical code sitting around isn't a good idea,
so fix that. JITIL had a couple of extra entry points into the JIT main
loop, so adjust the code appropriately.

Also fixes Issue 7186.

The new NOP emitter breaks when called with a negative count. As it

only 4 bytes long and need no BSWAP.
