Adhemerval Zanella 06be6368da nptl: Define __PTHREAD_MUTEX_{NUSERS_AFTER_KIND,USE_UNION} 
This patch adds two new internal defines to set the internal
pthread_mutex_t layout required by the supported ABIS:

  1. __PTHREAD_MUTEX_NUSERS_AFTER_KIND which control whether to define
     __nusers fields before or after __kind.  The preferred value for
     is 0 for new ports and it sets __nusers before __kind.

  2. __PTHREAD_MUTEX_USE_UNION which control whether internal __spins and
     __list members will be place inside an union for linuxthreads
     compatibility.  The preferred value is 0 for ports and it sets
     to not use an union to define both fields.

It fixes the wrong offsets value for __kind value on x86_64-linux-gnu-x32.
Checked with a make check run-built-tests=no on all afected ABIs.

	[BZ #22298]
	* nptl/allocatestack.c (allocate_stack): Check if
	__PTHREAD_MUTEX_HAVE_PREV is non-zero, instead if
	__PTHREAD_MUTEX_HAVE_PREV is defined.
	* nptl/descr.h (pthread): Likewise.
	* nptl/nptl-init.c (__pthread_initialize_minimal_internal):
	Likewise.

	(__PTHREAD_MUTEX_NUSERS_AFTER_KIND, __PTHREAD_MUTEX_USE_UNION): New

	(__pthread_internal_list): Check __PTHREAD_MUTEX_USE_UNION instead
	of __WORDSIZE for internal layout.
	(__pthread_mutex_s): Check __PTHREAD_MUTEX_NUSERS_AFTER_KIND instead
	of __WORDSIZE for internal __nusers layout and __PTHREAD_MUTEX_USE_UNION
	instead of __WORDSIZE whether to use an union for __spins and __list
	fields.
	(__PTHREAD_MUTEX_HAVE_PREV): Define also for __PTHREAD_MUTEX_USE_UNION
	case.
