m68k: minor bits, addq/subq works also on address regs, remove reference validity check in a_op_const_ref because we have fixref() later anyway

m68k: use MOVEA without size to load values to address regs. use a_op_const_reg in a_op_const_ref for smarter const loading when necessary

m68k: minor optimizations to g_proc_exit() - use LEA for stackpointer math which is better than ADDing large constants, also only modify the SP reg once

back to more conservative sign extension. this really needs separate handling for ColdFire and normal 68k, because the CF executes 32bit arithmetics only while normal 68k will do any size happily.

addressing improvements: fixref can swap base/index registers if better fits 68k pattern, less need to move around registers. also fix reference in a_op_const_ref.

+ added a size parameter to optimize_op_const and do a sign extension of the 'a' parameter up from the specified size, so that things like (i and $ffffffff) get optimized away the same way as (i and -1)
