    x86: Don't check if AVX512 template requires AVX512VL
    
    If the ZMM operand in an AVX12 template also allows XMM or ZMM, this
    template must require AVX512VL.  Drop the AVX512VL requirement check
    on such AVX512 templates.
    
            * config/tc-i386.c (check_VecOperands): Don't check if AVX512
            template requires AVX512VL.
