m68k: try to generate a bit smaller code in g_adjust_self; also changed two JMPs to S_NO from S_L, because JMP is unsized anyway

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: 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.
