Adhemerval Zanella 5712f8db26 nptl: Add tests for internal pthread_mutex_t offsets 
This patch adds a new build test to check for internal fields
offsets for user visible internal field.  Although currently
the only field which is statically initialized to a non zero value
is pthread_mutex_t.__data.__kind value, the tests also check the
offset of __kind, __spins, __elision (if supported), and __list
internal member.  A internal header (pthread-offset.h) is added
to each major ABI with the reference value.

Checked on x86_64-linux-gnu and with a build check for all affected
ABIs (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf,
hppa-linux-gnu, i686-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,
microblaze-linux-gnu, mips64-linux-gnu, mips64-n32-linux-gnu,
mips-linux-gnu, powerpc64le-linux-gnu, powerpc-linux-gnu,
s390-linux-gnu, s390x-linux-gnu, sh4-linux-gnu, sparc64-linux-gnu,
sparcv9-linux-gnu, tilegx-linux-gnu, tilegx-linux-gnu-x32,
tilepro-linux-gnu, x86_64-linux-gnu, and x86_64-linux-x32).

	* nptl/pthreadP.h (ASSERT_PTHREAD_STRING,
	ASSERT_PTHREAD_INTERNAL_OFFSET): New macro.
	* nptl/pthread_mutex_init.c (__pthread_mutex_init): Add build time
	checks for internal pthread_mutex_t offsets.
	* sysdeps/aarch64/nptl/pthread-offsets.h
	(__PTHREAD_MUTEX_NUSERS_OFFSET, __PTHREAD_MUTEX_KIND_OFFSET,
	__PTHREAD_MUTEX_SPINS_OFFSET, __PTHREAD_MUTEX_ELISION_OFFSET,
	__PTHREAD_MUTEX_LIST_OFFSET): New macro.
