i386.md (*sinxf2): Rename to *sinxf2_i387.

Browse Source 
* config/i386/i386.md (*sinxf2): Rename to *sinxf2_i387.
        (*cosxf2): Rename to cosxf2_i387.

        (*sindf2, *sinsf2): Extend operand 1 to XFmode.  Macroize patterns
        using X87MODEF12 mode macro. Rename patterns to
        *sin_extend<mode>xf2_i387.  Use SSE_FLOAT_MODE_P to disable patterns
        for SSE math.
        (*cosdf2, *cossf2): Ditto.
        (sincosdf3, sincossf3): Ditto.  Rewrite corresponding splitters
        to match extended input operands.

        (sincos<mode>3): New expander.

        (*sinextendsfdf2, *cosextendsfdf2, *sincosextendsfdf3): Remove
        insn patterns and corresponding splitters.
