i386.md (movsf_1): Enable pattern for standard 80387 constants before reload when optimizing for size.
* 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.
