patch adding -mlong-jump-table-offsets option for m68k

This is the crude patch I mentioned in an older comment, forward-ported to
trunk.  It's only a compile-time option for using long offsets, plus needed
adjustments here and there.

I haven't tried to implement CASE_VECTOR_SHORTEN_MODE since I don't think it's
useful without per-insn length attributes.

Why does the backend have three identical definitions of ASM_RETURN_CASE_JUMP?
