Adjust sizes between 64KB and 16MB and iterations based on length.
Remove incorrect uses of alloc_bufs since we're not interested in measuring
Linux clear_page time. Use getpagesize() - 1 instead of 4095 when
aligning within a page.

I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

The ORIG_SRC argument is likely a useless relic from the original
correctness tests that are not needed in the benchmarks. Remove the
argument and use S1 to point to the source to avoid confusion.
* benchtests/bench-memmove.c (do_one_test): Remove unused
ORIG_SRC.
(do_test): Adjust.
* benchtests/bench-memmove-large.c (do_one_test): Remove unused
ORIG_SRC.
(do_test): Adjust.
Make the memmove benchmarks (bench-memmove and bench-memmove-large)
print their output in JSON so that they can be evaluated using the
compare_strings.py script.
* benchtests/bench-memmove-large.c: Print output in JSON
format.
* benchtests/bench-memmove.c: Likewise.
The test run is unnecessary and interferes with the benchmark. The
tests are done during make check, so they're unnecessary here.
* benchtests/bench-memccpy.c (do_one_test): Remove checks.
* benchtests/bench-memchr.c (do_one_test): Likewise.
* benchtests/bench-memcpy-large.c (do_one_test): Likewise.

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