Signed comparisons now work correctly; sadly, Star Trek increases from 39656 to
39726 bytes. Note that the emulator doesn't set P/V correctly and all the tests
fail. Testing in z80ex works fine.

Use pop rather than inx;inx to retract the stack; consumes a register but
halves the number of calls. Reduces Star Trek from 39976 to 39771 bytes.

Teach the i80 code generator how to do left shifts by using dad hl; prevents it
from calling out to .sli2 for simple shifts. Shrinks Star Trek from 40055 bytes
to 39976.
