target/m68k: Fix address argument for EXCP_TRACE
According to the M68040 Users Manual, section 8.4.3,
Six word stack frame (format 2), Trace (and others) is
supposed to record the next insn in PC and the address
of the trapping instruction in ADDRESS.
Create gen_raise_exception_format2 to record the trapping
pc in env->mmu.ar. Update m68k_interrupt_all to pass the
value to do_stack_frame. Update cpu_loop to handle EXCP_TRACE.
