Use uint64_t and (uint64_t) 1 for 64-bit int
This patch replaces unsigned long int and 1UL with uint64_t and
(uint64_t) 1 to support ILP32 targets like x32.

	[BZ #17870]
	* nptl/sem_post.c (__new_sem_post): Replace unsigned long int
	with uint64_t.
	* nptl/sem_waitcommon.c (__sem_wait_cleanup): Replace 1UL with
	(uint64_t) 1.
	(__new_sem_wait_slow): Replace unsigned long int with uint64_t.
	Replace 1UL with (uint64_t) 1.
	* sysdeps/nptl/internaltypes.h (new_sem): Replace unsigned long
	int with uint64_t.
