Subject: unroll.c: Removed.

	* unroll.c: Removed.
	* loop.h: Removed.
	* Makefile.in (LOOP_H, unroll.o): Removed.
	(toplev.o, passes.o, stmt.o, integrate.o, loop.o): Remove LOOP_H
	dependency.
	* alias.c (init_alias_analysis): Remove flag_old_unroll_loops
	reference.
	* cfgloop.h (LOOP_PREFETCH, loop_optimize): Moved from loop.h.
	* common.opt (fold-unroll-loops, fold-unroll-all-loops): Removed.
	* loop.c: Do not include loop.h.
	(LOOP_INFO, LOOP_MOVABLES, LOOP_REGS, LOOP_IVS, INSN_LUID,
	REGNO_FIRST_LUID, REGNO_LAST_LUID, enum g_types, struct induction,
	struct iv_class, enum iv_mode, struct iv, REG_IV_TYPE, REG_IV_INFO,
	REG_IV_CLASS, struct loop_ivs, struct loop_mem_info, struct loop_reg,
	struct loop_regs, struct loop_movables, struct loop_info): Moved
	from loop.h.
	(back_branch_in_range_p, fold_rtx_mult_add, biv_total_increment,
	reg_dead_after_loop, final_biv_value, loop_find_equiv_value,
	find_common_reg_term, loop_iterations, final_giv_value): Moved
	from unroll.c.

	loop_insn_first_p, get_condition_for_loop,
	loop_insn_emit_before, loop_insn_hoist,
	loop_insn_sink): Made static.
	(loop_invariant_p): Made static.  Removed flag_old_unroll_loops
	reference.
	(strength_reduce): Do not call unroller.
	(record_giv): Do not initialize unrolled field.
	(prescan_loop): Do not set loop_info->preconditioned.
	* passes.c: Do not include loop.h.
	(rest_of_handle_loop_optimize): Do not call unroller.
	* predict.c: Do not include loop.h.
	* rtl.h (NOTE_PRECONDITIONED): Removed.
	* stmt.c: Do not include loop.h.
	* toplev.c: Do not include loop.h.
	(process_options): Do not handle flag_old_unroll_loops.
