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.
