* x86: Add support to build wcscpy with explicit ISA levelNoah Goldstein2022-07-161-0/+31
1. Add ISA level build guards to different implementations. - wcscpy-ssse3.S is used as ISA level 2/3/4. - wcscpy-generic.c is only used at ISA level 1 and will only build if compiled with ISA level == 1. Otherwise there is no reason to include it as we will always use wcscpy-ssse3.S 2. Refactor the ifunc selector and ifunc implementation list to use the ISA level aware wrapper macros that allow functions below the compiled ISA level (with a guranteed replacement) to be skipped. Tested with and without multiarch on x86_64 for ISA levels: {generic, x86-64-v2, x86-64-v3, x86-64-v4} And m32 with and without multiarch.
