Don't set pending boot flag on "stop".

And rename to boot pending, not "boot successful."
Avoid forcing nearest/disabling linear if possible.

If we know that the test is trivially true, we don't need to worry about
the test.  May help #4405.
Eat cycles and resched in sceGeContinue().

Fixes the gpu/ge/queue test.
Make sure not to break when GE debugger closed.

Also, try to fix a might-be race condition.

Add notes for proper NaN handling in vmin/vmax.
armjit: Correct disabled vslt NaN handling.

Can possibly enable?
armjit: Fix D-prefix sat clamp NAN handling.

They should leave NAN alone.
x86jit: Correctly handle NaNs in vfpxd sat clamps.

May be a small performance jit, but we've seen games with bugs because of
NaNs recently, so better to be safe.
x86jit: Correct vsat0/vsat1 handling.
