[PATCH] D20991: Set machine block placement hot prob threshold for both static and runtime profile.

I'm still putting the triangle shape handling code outside as the logic is not related to PGO. Even with static profile, the triangle-shaped CFG should have a more relaxed condition to be topologically placed.

Added unittest to cover all cases.
