* config/i386/i386.md (movsf_1): Enable pattern for standard

	80387 constants before reload when optimizing for size.
	(*movdf_nointeger, *movdf_integer): Ditto.
	(*movxf_nointeger, *movxf_integer): Disable patterns for standard
	80387 constants before reload when not optimizing for size.

	(*fop_xf_4_i387, *fop_xf_5_i387, *fop_xf_6_i387): Avoid float
	extension of XFmode input operands.
