target/m68k: call gen_raise_exception() directly if single-stepping in gen_jmp_tb()
In order to consolidate the single-step exception handling into a single
helper, change gen_jmp_tb() so that it calls gen_raise_exception() directly
instead of gen_exception(). This ensures that all single-step exceptions are
now handled directly by gen_raise_exception().
