Windows Register List fixes

make the rightclick work in the registerlist for all displayed registers.
The LO HI and PC registers couldn't be rightclicked previously.

Also, if you rightlick a valid row and then rightclick on the leftmost 16
pixels you'd get the popup menu for the old selection (even on invalid y
indices).

Make the "change register value"-dialog start with '0x' because otherwise
values starting with an alphabetical hexadecimal symbol will yield
be parsed as a symbol instead of a number and yield 'unknown symbol'
Omit a few commands from "DL Unknown" in debug.
Switch to 59.94 fps rather than 60.
Track hcount as an integer, not a double.

Since it's even with NTSC.  Makes much more sense.
Implement vocp on ARM and x86.
Optimize multiple sv.s and lv.s calls on ARM. Also some cleanup.
Get rid of bool disablePrefixes in ARM build (already gone in x86)
Some scaffolding for a future VFPU-on-NEON implementation
