In most cases the simple/stupid/builtin functions were in there to
benchmark optimized implementations against. Only in some cases the
functions are used to check expected results.
Remove these tests from IMPL() and only keep them in wherever they're
used for a specific purpose, e.g. to generate expected results.
This improves timing of `make subdirs=string` by over a minute and a
half (over 15%) on a Whiskey Lake laptop.

Looks like an oversight in memcpy tests resulted in s2 and s1 not being
swapped for the second iteration of the memcpy test. Fix it. Also fix
a formatting nit.

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.
remote: *** 912-#endif
remote: *** 913:
remote: *** 914-
remote: *** error: lines with trailing whitespace found
...
remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

commit d585ba47fcda99fdf228e3e45a01b11a15efbc5a
Author: Noah Goldstein <goldstein.w.n@gmail.com>

string: Make tests birdirectional test-memcpy.c
Add tests that had src/dst non 4-byte aligned. Since src/dst are
initialized/compared as uint32_t type which is 4-byte aligned this can
break on some targets.
Fix the issue by specifying a new non-aligned 4-byte
`unaligned_uint32_t` for src/dst.
Another alternative is to rely on memcpy/memcmp for
initializing/testing src/dst. Using memcpy for initializing in memcpy
tests, however, could lead to future bugs.

No bug.
This commit splits test-memcpy.c into test-memcpy.c and
test-memcpy-large.c. The idea is parallel builds will be able to run
both in parallel speeding up the process.
