Pthread lib Profiling

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.

[BUG]

NAS benchmark BT class B won't run on v-test-5038ki;
It runs on qemu and virtualbox;
Guess is :
virtual environment has initialized memory (to 0) while on real machine, it's not; and when you check
some ptr == NULL, it's not NULL. Subsequently causes GP.
