x86_64: Implement evex512 version of memchr, rawmemchr and wmemchr
This patch implements following evex512 version of string functions. evex512 version takes up to 30% less cycle as compared to evex, depending on length and alignment. - memchr function using 512 bit vectors. - rawmemchr function using 512 bit vectors. - wmemchr function using 512 bit vectors. Code size data: memchr-evex.o 762 byte memchr-evex512.o 576 byte (-24%) rawmemchr-evex.o 461 byte rawmemchr-evex512.o 412 byte (-11%) wmemchr-evex.o 794 byte wmemchr-evex512.o 552 byte (-30%) Placeholder function, not used by any processor at the moment.
