Changelog:
- massive cleanups and optimizations on the PPU core
- ~9% speedup over v099 official
This is pretty much it for the low-hanging fruit of speeding up higan. Any
more gains from this point will be extremely hard-fought, unfortunately.

Changelog:
- SFC: fixed a regression on auto joypad polling due to missing
parentheses
- SFC: exported new PPU::vdisp() const -> uint; function [1]
- SFC: merged PPU MMIO functions into the read/write handles (as
I previously did for the CPU)
- higan: removed individual emulator core names (bnes, bsnes, bgb, bgba,
bws) [2] Forgot:
- to remove /tomoko from the about dialog
[1] note that technically I was relying on the cached, per-frame
overscan setting when the CPU and light guns were polling the number of
active display scanlines per frame. This was technically incorrect as
you can change this value mid-frame and it'll kick in. I've never seen
any game toggle overscan every frame, we only know about this because
anomie tested this a long time ago. So, nothing should break, but ...
you know how the SNES is. You can't even look at the code without
something breaking, so I figured I'd mention it >_>
[2] I'll probably keep referring to the SNES core as bsnes anyway.
I don't mind if you guys use the b<system> names as shorthand. The
simplification is mostly to make the branding easier.
