Attempt to follow branches to a max # of ops.

Seems to make it slower also. Maybe taking the branch would be better...

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 .

Just in case - could be a jump target, maybe? Never seen it, though.

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.

NOOP seems very common so this should already benefit speed a bit.

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.
