* sched-int.h (struct _haifa_deps_insn_data): New members cond
and reverse_cond.
(INSN_COND, INSN_REVERSE_COND): New macros.
* sched-deps.c (deps_analyze_insn): Call sched_get_condition_with_rev
once.
(sched_get_condition_with_rev): Cache the results, and look them up
if possible.
(sched_analyze_insn): Destroy INSN_COND of previous insns if they
are clobbered by the current insn.
* target.def (exposed_pipline): New sched data hook.
* doc/tm.texi.in: TARGET_SCHED_EXPOSED_PIPELINE: Add hook.
* doc/tm.texi: Regenerate.
