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.
