Bug fixed: cg generated instructions like "and.l #2,a4", which are
...
not allowed on the 68000.
The condition "inreg($...) < 2" is added to every EM-pattern that
accesses local non-register variables. So the ordering of the
patterns for regvar/non-regvar is no longer important.

Bugs fixed for the following patterns:
...
lol loc 255 and 2 (byte order was wrong)
loc x beq , 0 < x < 128 (was 0 < x < 256)
loc x bne (idem).
These bugs were introduced in version 2.2.

bug fixed: generate "add.l #65536,a1" rather than "lea 65536(a1),a1".
...
The latter form is only generated for constants that fit in a word.
