df32c99be6 Attempt to follow branches to a max # of ops. 
Seems to make it slower also.  Maybe taking the branch would be better...
hmmph.

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.

b5fe67eb3d If the out is RA, delay slot isn't nice for jal.

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

44b5adeaac Properly jit the break instruction. 
Otherwise, it just keeps on going past it.
We never want to hit this anyway, but it's good to know if we do.

75cbe18afc Simplify nice delay slot detect, and yes for noop. 
NOOP seems very common so this should already benefit speed a bit.

2eba209f64 Move around the jit nice delay slot logic. 
Nice delay slots don't not save flags, they run before the CMP.

a9d0390426 Adjust downcount before syscalls, not after. 
This makes jit slightly slower for syscalls, but it's minor and makes
sure jit and interpreter timing are determistically the same.
