* config/i386/i386.md (float<SWI48x:mode><MODEF:mode>2) Enable
	DImode for x87 on 32bit targets.  Conditionally disable x87 modes
	with X87_ENABLE_FLOAT.  Remove preparation code.
	(*float<SWI48:mode><MODEF:mode>2): Rename from
	*float<SWI48:mode><MODEF:mode>2_mixed.  Handle x87, SSE and mixed
	math using "enabled" attribute.
	(*floatdi<MODEF:mode>2_i387): Rename from
	*float<SWI48x:mode><MODEF:mode>2_i387.  Handle only DImode and
	enable for 32bit targets only.
	(floatdi<X87MODEF:mode>2_i387_with_xmm pre-reload splitter): New
	splitter.
	(floatdi<X87MODEF:mode>2_i387_with_xmm): Use register_operand
	as operand 1 predicate.  Rewrite as define_insn_and_split.
	(floatdi<X87MODEF:mode>2_i387_with_xmm memory input splitter): Remove.
