ee66596b8d x86jit: Micro optimize slt* a bit. 
This improves their performance and hopefully latency.  It also avoids
filling registers that are not likely to be used again.

57caa95273 x86jit: Implement round.w.s and friends. 
They are not terribly fast, though, updating MXCSR.

3908e0f445 x86jit: Small optimization for add.s f1, f2, f2. 
Doubles the speed of that particular case.  Biggest difference is not
loading fd for no reason.

Same reg is probably a common case, improves micro benchmark.

1917d946ea x86jit: Micro optimize cvt.s.w a bit. 
This implementation is about 5x faster for micro benchmarks.  Little
impact to overall perf in games I tested, though.

671dee85c7 x86jit: Micro optimize vi2f a little bit. 
This didn't help overall perf much but micro benchmarks are better.

0e646f748a x86jit: Implement vi2x instructions. 
Also, my opcodes were wrong in the test (shifted the pair bit the wrong
way, oops.)

AFAICT, there's no reason PSRAD/etc. were not encoding REX...

0d36d4e082 Add a helper to reduce duplicate code. 
This is not performance critical.  I wonder if compilers can inline
closures?

3% improvement in Grand Knights History.  I know other games use these
too.

717cf25f0d x86jit: Use our sincos funcs for VV2Op as well. 
Small (0.7%) speedup in Gods Eater Burst.  There's probably SSE
approximations we could use instead, but those will also need at least xmm
reg flushing/thunking.

At least this avoids flushing gprs, etc.  The sin and cos ops are fairly
common.

01f9521dc5 jit: Invalidate blocks even if they end unevenly. 
This allows blocks to start and end where ever they need, which should be
good for replacements and for continuing.

e3a04aa2d2 x86jit: Preload sp and similar regs used often. 
This can help us avoid using a temporary.

Very tiny performance improvement.

6fae78cd3f x86jit: Fix a bug in branch continuing. 
When we predict it won't take a likely delay slot, we'd lose our register
allocation state.

2f598e8f38 jit: Statically jump for fixed branches. 
This handles both loops (first step is known) and static branches (some
code uses them instead of jumps, and we disassemble that to "b".)

Not likely to be a big improvement, but might help if the branch predictor
was wrong.

This is as opposed to continuing, which would build a larger jit block.

eab010a0c0 x86 JIT: Sacrifice a register for a pointer to the MIPS context. Shrinks emitted x86 code considerably. 
Nice in 64-bit, but might be a bit too much in 32-bit though... Needs testing.

Default: force flush to zero (for RunFast mode.)  But now it's an ini
option so we can more easily compare armjit differences.
