commit fd242dafbd82cd391306358dd3b98fc27d5f5f68
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Wed Jul 21 15:44:46 2021 -0400

    Move xx* builtins to vsx.md.
    
    I noticed that the xx built-in functions (xxspltiw, xxspltidp, xxsplti32dx,
    xxeval, xxblend, and xxpermx) were all defined in altivec.md.  However, since
    the XX instructions can take both traditional floating point and Altivec
    registers, these built-in functions should be in vsx.md.
    
    This patch just moves the insns from altivec.md to vsx.md.
    
    I also moved the VM3 mode iterator and VM3_char mode attribute from altivec.md
    to vsx.md, since the only use of these were for the XXBLEND insns.
