	Revert:
	2007-09-05  Laurynas Biveinis  <laurynas.biveinis@gmail.com>
	* regrename.c (copyprop_hardreg_forward_1): New variable next. Use
	FOR_BB_INSNS_SAFE instead of for loop.
	* cse.c (cse_extended_basic_block): Likewise.
	* postreload.c (reload_cse_regs_1): New variable next. Make sure
	that the for loop does not invoke NEXT_INSN on a deleted insn.
	* function.c (instantiate_virtual_regs): Likewise.
	* lower-subreg.c (remove_retval_note): Likewise.
	(decompose_multiword_subregs): Use FOR_BB_INSNS_SAFE instead of
	FOR_BB_INSNS.
	* emit-rtl.c (remove_insn): Set NEXT_INSN and PREV_INSN to NULL on
	a deleted insn.
	* cfgrtl.c (delete_insn): Set JUMP_LABEL to NULL on a deleted
	insn, if it's a jump.
	(try_redirect_by_replacing_jump): New variable jump_p. Call
	tablejump_p before delete_insn_chain.
	* reload1.c (reload): New variable next. Make sure that the for
	loop does not invoke NEXT_INSN on a deleted insn.
	(fixup_eh_region_note): Make the loop terminate if i becomes NULL.
	(delete_output_reload): New variable prev. Make sure the the for
	loops do not invoke PREV_INSN on a deleted insn.
