* sched-int.h (struct deps): Add max_reg, reg_last_in_use; merge
reg_last_uses, reg_last_sets, reg_last_clobbers into struct deps_reg.
* sched-deps.c (sched_analyze_1): Update uses of struct deps.
(sched_analyze_2, sched_analyze_insn): Likewise.
(sched_analyze, init_deps): Likewise.
(free_deps): Likewise. Iterate with EXECUTE_IF_SET_IN_REG_SET.
* sched-rgn.c (propagate_deps): Likewise. Remove max_reg argument.
(compute_block_backward_dependences): Update propagate_deps call.
