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. * sysdeps/alpha/nptl/pthread-offsets.h: Likewise. * sysdeps/arm/nptl/pthread-offsets.h: Likewise. * sysdeps/hppa/nptl/pthread-offsets.h: Likewise. * sysdeps/i386/nptl/pthread-offsets.h: Likewise. * sysdeps/ia64/nptl/pthread-offsets.h: Likewise. * sysdeps/m68k/nptl/pthread-offsets.h: Likewise. * sysdeps/microblaze/nptl/pthread-offsets.h: Likewise. * sysdeps/mips/nptl/pthread-offsets.h: Likewise. * sysdeps/nios2/nptl/pthread-offsets.h: Likewise. * sysdeps/powerpc/nptl/pthread-offsets.h: Likewise. * sysdeps/s390/nptl/pthread-offsets.h: Likewise. * sysdeps/sh/nptl/pthread-offsets.h: Likewise. * sysdeps/sparc/nptl/pthread-offsets.h: Likewise. * sysdeps/tile/nptl/pthread-offsets.h: Likewise. * sysdeps/x86_64/nptl/pthread-offsets.h: Likewise.
