x86jit: Implement round.w.s and friends.

They are not terribly fast, though, updating MXCSR.

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.

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.

jit: Avoid applying/restoring the rounding mode.
...
If the game never sets it, we can skip around syscalls, interpreter,
replacements, etc.

jit: Rename the rounding mode funcs to clarify.

They apply/restore the value, set/clear is confusing.

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

x86jit: Maintain the rounding mode always.
...
This should be less often than doing it per block that uses fpu, unless
the game doesn't use fpu much at all.

x86jit: Implement cvt.w.s.

Not really used that often, anyway, but easy enough and good for testing
that we set the rounding mode correctly.

x86jit: Use a faster safemem fallback.
...
Really helps performance in games that use uncached addresses a lot,
without really impacting performance of most games which don't.
Of course, fastmem is faster.
