Add hotkeys to select save state slots and to save/load the currently selected slots.
JIT: simpler fallback conditions for load/store float

I wasn't really thinking when I wrote these; d/s are for float registers, not
gprs.
JIT: implement remaining psq_l/st instruction variants

These are used in at least a few popular games, including Super Smash Bros.
Brawl.
Debugger: make opcode search a bit better

Search a wider range (not all games fit in the originally searched range).
Print a notice if the opcode isn't found, instead of silently failing.
FrameTools: Set focus on Windows via CFrame::SetFocus
JIT: support byte-reversed stores/loads

4 more instructions down.

Store ones should be pretty well-tested; load ones seem to almost never be
used. I found them in Turok Evolution, so I was able to check code generation,
but the relevant code didn't seem to be called.
JIT: change eieio and tlbsync to DoNothing

The interpreter functions for these are no-ops anyways.
Also add some missing DoNothings to the ARM64 JIT.
