PR optimization/11320
* sched-int.h (struct deps) [reg_conditional_sets]: New field.
(struct sched_info) [compute_jump_reg_dependencies]: New prototype.
* sched-deps.c (sched_analyze_insn) [JUMP_INSN]: Update call to
current_sched_info->compute_jump_reg_dependencies. Record which
registers are used and which registers are set by the jump.
Clear deps->reg_conditional_sets after a barrier.
Set deps->reg_conditional_sets if the insn is a COND_EXEC.
Clear deps->reg_conditional_sets if the insn is not a COND_EXEC.
(init_deps): Initialize reg_conditional_sets.
(free_deps): Clear reg_conditional_sets.
* sched-ebb.c (compute_jump_reg_dependencies): New prototype.
Mark registers live on entry of the fallthrough block and conditionally
set as set by the jump. Mark registers live on entry of non-fallthrough
blocks as used by the jump.
* sched-rgn.c (compute_jump_reg_dependencies): New prototype.
Mark new parameters as unused.
