rtlanal: dead_or_set_regno_p should handle CLOBBER (PR83424)
In PR83424 combine's move_deaths puts a REG_DEAD note in the wrong place
because dead_or_set_regno_p does not account for CLOBBER insns. This
fixes it.
PR rtl-optimization/83424
* rtlanal.c (dead_or_set_regno_p): Handle CLOBBER just like SET.
