commit 8c1e657d27fb51e3fa592b3e9ad1f2529092ef1e

    Move XXEVAL from altivec.md to vsx.md.
    
    This patch moves the XXEVAL support from altivec.md to vsx.md.  Given
    the instruction support all VSX registers, vsx.md is a more proper place
    for this instruction.
    
    The xxeval insn used "altivec_register_operand".  I replaced this with
    "vsx_register_operand" since the instruction takes any VSX register.
    
    I was chatting with Pat Haugen, he said that the insn type should be
    "vecperm" and not "vecsimple", so I changed this as well.

            * config/rs6000/altivec.md (UNSPEC_XXEVAL): Move to vsx.md.
            (xxeval): Move to vsx.md.
            * config/rs6000/vsx.md (UNSPEC_XXEVAL): Move from altivec.md.
            (xxeval): Move from altivec.md.  Change altivec_register_operand
            to vsx_register_operand.  Change insn type to vecperm.
