	* ssa.c (convert_to_ssa): Eliminate dead code when calling
	life_analysis.
	(convert_from_ssa): Call compute_bb_for_insn before life_analysis.
	(for_each_successor_phi): Change parameter to basic_block.
	(coalesce_regs_in_successor_phi_nodes): Likewise.
	(coalesce_regs_in_copies): Likewise.
	(compute_coalesced_reg_partition): Use basic_block instead of index.
	* rtl.h (convert_to_ssa): Delete.
	(convert_from_ssa): Likewise.
	(successor_phi_fn): Likewise.
	(for_each_successor_phi): Likewise.
	(in_ssa_form): Likewise.
	* basic-block.h (convert_to_ssa): Moved from rtl.h.
	(convert_from_ssa): Likewise.
	(successor_phi_fn): Likewise.
	(in_ssa_form): Likewise.
	(for_each_successor_phi): Likewise.  Change parameter to basic_block.
	* flow.c (calculate_global_regs_live): Pass a basic_block to
	for_each_successor_phi.
