8d0dca71fe jit: Rename the rounding mode funcs to clarify. 
They apply/restore the value, set/clear is confusing.

925557ed47 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.

dc91dc1ce8 x86jit: Support fpu rounding modes for mul, etc. 
Fixes Gods Eater Burst loading PSP savedata, but can no longer load old
savedata.

Makes it a bit cleaner and potentially safer.

1cb7965cb1 Jit feature preparation: Introduce "proxy blocks". 
When these are invalidated, the block they point to gets invalidated too.

Will be useful to implement various types of block merging and function inlining
without affecting correctness of cache clears etc.

Also, with this commit we can now fully inline replaced functions. fabsf() boils
down to 1-2 instructions and the block continues, for example.

359110f010 x86/armjit: Add jump following (off by default.) 
Inlines function calls up to a certain extent.  Allows us to get
immediates all the way to a syscall, for example, usually.

Not sure if faster.

aacb31bc18 armjit: Copy over (disabled) immbranch optim. 
This does a little loop unrolling.  Costs a bit more cache space, but
avoids flushing regs for longer.

5a95e267fb Add an optimization to discard registers at the end of functions when possible. 
Works in some games but crashes many so hiding it for now. Do not add UI.

732ae13ebb Fast path CallSyscall where possible. 
It seems we're spending a decent amount of time there, which isn't
entirely unexpected.  We can eliminate some things easily.

2e8ef3027f Write the retaddr to rd, not always ra, in jalr. 
Thanks go entirely to @Kingcom for pointing this out.

Don't know of any games not using RA as the rd.

df32c99be6 Attempt to follow branches to a max # of ops.

e639f8d15f Handle branches in VFPU delay slots better. 
Based on tests on a PSP, all branches are attempted.  The behavior is
technically undefined.

It seems to take the delay slot's target if they differ and both pass.
This is the behavior the interpreter has, but it's more work in jit.

Since only a couple games seem to do this, and clearly expect this
behavior, this fixes all known cases of #1926.

bab7947be6 Read delay slots as instructions not mem. 
Just in case - could be a jump target, maybe?  Never seen it, though.
