Break up Ypos loop into pre/loop/post segment to optimize. Saved ~5,000 cycles/sec. When applied to the other routines will save a few thousand more cycles

Inline all functions that are only called once
...
Eliminates the JSR/RTS overhead for the copy functions. Combined
with the other streamlining, we save around 60 - 70 cycles per
bank, or a total savings of around 10,000 cycles per seconds when
running at full screen.
This doesn't really change the FPS, but just gives some cycles
back to the main application logic.
