Update CPC port to SDCC 4.2.0
This version of SDCC introduces a new calling convention where some
values can be passed in registers. Adjust the assembler code
accordingly, making it smaller and faster.
Some things are not working quirte right yet:
- The routine to clear a rectangle isn't working correctly
- The keyboard input also does not seem to work completely
