Instead of using parameterised rsts for stack access, add a huge swathe of
automatically built helper tools. Star Trek goes up from 40243 to 40779 bytes,
but should be a lot faster.

Replace the non-working Z80 style signed comparison sign adjustment with
something which actually works on the 8080. Sadly, Star Trek is up to
40243 bytes again.

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.

Add rst 3 to get the address of a frame variable; lots of rule overhaulage.
Reduces Star Trek from 41821 to 41055 bytes.

Somehow the implementation of rst 2 got lost, with hilarious results. Also fix
some register corruption issues (I hope).

rst 1 now takes an eight-bit parameter, not a 16 bit one. Reduces Star Trek
again from 43205 to 42339 bytes.

Experimentally use rst 1 to optimise frame variable loads. Reduces Star Trek
from 43892 to 43205 bytes.
