* regstat.c (regstat_bb_compute_ri): Take new local_live_last_luid
argument. Simplify calculation of REG_LIVE_LENGTH for regnos that
die in the basic block. Correctly top off REG_FREQ and
REG_FREQ_CALLS_CROSSED.
Remove do_not_gen.
(regstat_compute_ri): Allocate and free local_live_last_luid.
Remove do_not_gen.
(regstat_bb_compute_calls_crossed): Correctly top off
REG_FREQ_CALLS_CROSSED.
