Improve generic strpbrk performance
With now a faster strcspn implementation, it is faster to just use it with some return tests than reimplementing strpbrk itself. As for strcspn optimization, it is generally at least 10 times faster than the existing implementation on bench-strspn on a few AArch64 implementations. Also the string/bits/string2.h inlines make no longer sense, as current implementation will already implement most of the optimizations. Tested on x86_64, i386, and aarch64. * string/strpbrk.c (strpbrk): Rewrite function. * string/bits/string2.h (strpbrk): Use __builtin_strpbrk. (__strpbrk_c2): Likewise. (__strpbrk_c3): Likewise. * string/string-inlines.c [SHLIB_COMPAT(libc, GLIBC_2_1_1, GLIBC_2_24)] (__strpbrk_c2): Likewise. [SHLIB_COMPAT(libc, GLIBC_2_1_1, GLIBC_2_24)] (__strpbrk_c3): Likewise.
