x86: Add avx2 optimized functions for the wchar_t strcpy family Implemented: wcscat-avx2 (+ 744 bytes wcscpy-avx2 (+ 539 bytes) wcpcpy-avx2 (+ 577 bytes) wcsncpy-avx2 (+1108 bytes) wcpncpy-avx2 (+1214 bytes) wcsncat-avx2 (+1085 bytes) Performance Changes: Times are from N = 10 runs of the benchmark suite and are reported as geometric mean of all ratios of New Implementation / Best Old Implementation. Best Old Implementation was determined with the highest ISA implementation. wcscat-avx2 -> 0.975 wcscpy-avx2 -> 0.591 wcpcpy-avx2 -> 0.698 wcsncpy-avx2 -> 0.730 wcpncpy-avx2 -> 0.711 wcsncat-avx2 -> 0.954 Code Size Changes: This change increase the size of libc.so by ~5.5kb bytes. For reference the patch optimizing the normal strcpy family functions decreases libc.so by ~5.2kb. Full check passes on x86-64 and build succeeds for all ISA levels w/ and w/o multiarch. 2022-11-09 01:38:41 +00:00			`#ifndef WCSNCAT`
