Fix rawmemchr build with GCC 8.
The default rawmemchr implementation uses memchr with size (size_t)-1,
which produces a warning with current GCC mainline. The warning seems
reasonable for normal code, so this patch uses the DIAG_* macros to
disable it.
Tested (compilation of glibc only) with build-many-glibcs.py for
arm-linux-gnueabi and powerpc64le-linux-gnu, two architectures for
which the build was previously failing. Note that the glibc testsuite
will still fail to build with GCC mainline because of
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80669>.
* string/rawmemchr.c: Include <libc-diag.h>.
(RAWMEMCHR): Disable -Wstringop-overflow around call to memchr
with size (size_t)-1.
