Drop realloc_bufs in favour of making alloc_bufs transparently
reallocate the buffers if it had allocated before. Also consolidate
computation of buffer lengths so that they don't get repeated on every
reallocation.
* benchtests/bench-string.h (buf1_size, buf2_size): New
variables.
(init_sizes): New function.
(test_init): Use it.
(alloc_buf, exit_error): New functions.
(alloc_bufs): Use ALLOC_BUF.
(realloc_bufs): Remove.
* benchtests/bench-memcmp.c (do_test): Adjust.

* benchtests/bench-memset-walk.c (do_test): Likewise.

Keeping the same buffers along with copying the same size of data into
the same location means that the first routine is typically the
slowest since it has to bear the cost of fetching data into to cache.
Reallocating buffers stabilizes numbers by a bit.
* benchtests/bench-string.h (realloc_bufs): New function.
(test_init): Call it.
* benchtests/bench-memset-large.c (do_test): Likewise.
* benchtests/bench-memset.c (do_test): Likewise.

Make the memset benchmarks (bench-memset and bench-memset-large) print
their output in JSON so that they can be evaluated using the
compare_strings.py script.
* benchtests/bench-memset-large.c: Print output in JSON
format.

The test run is unnecessary and interferes with the benchmark. The
tests are done during make check, so they're unnecessary here.

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.
