Vasily Leonenko 9aa134dc2d [PR] Instrumentation: use TryLock for SimpleHashTable getter ...

Summary:
This commit introduces TryLock usage for SimpleHashTable getter to
avoid deadlock and relax syscalls usage which causes significant
overhead in runtime.
The old behavior left under -conservative-instrumentation option passed
to instrumentation library.
Also, this commit includes a corresponding test case: instrumentation of
executable which performs indirect calls from common code and signal
handler.

Note: in case if TryLock was failed to acquire the lock - this indirect
call will not be accounted in the resulting profile.
