i386.md (pushsf splitter): Pass curr_insn to find_constant_src. 

	* config/i386/i386.md (pushsf splitter): Pass curr_insn to
	find_constant_src.  FAIL if find_constant_src returns NULL_RTX.
	(mem->fpreg splitters): Ditto.
	(general_operand->nonimmediate_operand splitter): Use explicit modes.
	Disable DFmode for TARGET_64BIT.
