Adjust benchtests to new support library.
...
This patch basically replaces the test-skeleton.c inclusion by
support/test-driver.c and also minor adjustments in bench-string.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.
* benchtests/bench-string.h (TEST_FUNCTION): Use name without
parenthesis.
(CMDLINE_PROCESS): Define using function instead of macro.
* benchtests/bench-memccpy.c: Include <support/test-driver.c> instead
of test-skeleton.

Improve strtok and strtok_r performance. Instead of calling strpbrk which
...
calls strcspn, call strcspn directly so we get the end of the token without
an extra call to rawmemchr. Also avoid an unnecessary call to strcspn after
the last token by adding an early exit for an empty string. Change strtok
to tailcall strtok_r to avoid unnecessary code duplication.
Remove the special header optimization for strtok_r of a 1-character
constant string - both strspn and strcspn contain optimizations for this
case. Benchmarking this showed similar performance in the worst case,
but up to 5.5x better performance in the "found" case for large inputs.
* benchtests/bench-strtok.c (oldstrtok): Add old implementation.
* string/strtok.c (strtok): Change to tailcall __strtok_r.
* string/strtok_r.c (__strtok_r): Optimize for performance.
* string/string-inlines.c (__old_strtok_r_1c): New function.
* string/bits/string2.h (__strtok_r): Move to string-inlines.c.

Make strtok benchmark competive.
...
We include a generic version of strtok to result which could be faster
when underlying primitives are better optimized than current version.
