x86: Add support for VEC_SIZE == 64 in strcmp-evex.S impl
Unused at the moment, but evex512 strcmp, strncmp, strcasecmp{l}, and
strncasecmp{l} functions can be added by including strcmp-evex.S with
"x86-evex512-vecs.h" defined.
In addition save code size a bit in a few places.
1. tzcnt ... -> bsf ...
2. vpcmp{b|d} $0 ... -> vpcmpeq{b|d}
This saves a touch of code size but has minimal net affect.
Full check passes on x86-64.
