Mine.
1. I have vague recollections of insns that set apparently-dead hw regs
remaining and being relevant for debug stuff, but I no longer remember the
details, and I'm not sure it had to do with the code at hand anyway, or whether
it justifies the current difference. I'll have to look into that.
2. Yeah, we ought to cleanup_auto_inc_dec the debug expr. I'll attach the
patch I'm testing momentarily.
