* dominance.c: New file.
* Makefile.in (OBJS): Add dominance.o.
* flow.c (compute_flow_dominators): Remove.
(compute_immediate_dominators): Remove.
(compute_immediate_postdominators): Remove.
* basic-block.h: Remove their prototypes.
(calculate_dominance_info): Add prototype.
* dce.c (eliminate_dead_code): Change calls to above functions.
Don't compute dominators but only immediate dominators.
* flow.c (flow_loops_find): Change callers.
* gcse.c (compute_code_hoist_data): Likewise.
* haifa-sched.c (schedule_insns): Likewise.
* ifcvt.c (if_convert): Likewise.
* ssa.c (convert_to_ssa): Likewise, and only compute immediate
dominators.
