Use instrument.c to profile the whole pthread library by wrap functions with NK_PROFILE_ENTRY and NK_PROFILE_EXIT.

From MG benchmark result, pte_cancellable_wait is taking the most of the time(basically anything that is using pte_osSemaphorePend), followed by spin_lock and sched_yield(nk_yield). But interestingly, pte_osSemaphorePend is not taking that much time as indicated by which uses it.
