x86_64: Implement evex512 version of strlen, strnlen, wcslen and wcsnlen This patch implements following evex512 version of string functions. Perf gain for evex512 version is up to 50% as compared to evex, depending on length and alignment. Placeholder function, not used by any processor at the moment. - String length function using 512 bit vectors. - String N length using 512 bit vectors. - Wide string length using 512 bit vectors. - Wide string N length using 512 bit vectors.
