History
Noah Goldstein 192979ee35 x86: Add support to build wcscpy with explicit ISA level 
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.
