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)
