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.

Complete masked tile rendering implementation
...
The core data tables were reworked to pre-reverse all of the
entries to directly match the right-to-left ordering of the code
fields. This simplified some code but was required for register
reuse in the masked tile renderer.
Also fixed several offset calculation issues in the masked tile
renderer.
