	* df-scan.c (df_def_record_1): Assert a parallel must contain an
	EXPR_LIST at this point.  Receive the LOC and move its extraction...
	(df_defs_record): ... here. Change if-else to a switch statement.
	(df_find_hard_reg_defs, df_find_hard_reg_defs_1): New.
	(df_get_call_refs): Changed defs_generated from bitmap to HARD_REG_SET
	and compute it from df_find_hard_reg_defs(). Record DF_REF_BASE
	DEFs in REGNO order. Use HARD_REG_SET instead of bitmap for
	regs_invalidated_by_call.
	(df_insn_refs_collect): Record DF_REF_REGULAR DEFs after
	df_get_call_refs().
