Alexander Markov 2b8e149999 [vm/kernel/tfa] Improve efficiency of type flow analysis 
* _ReceiverTypeBuilder class is introduced to create receiver type more
  efficiently (without using union operations and creating intermediate
  types).

* Certain tracing prints are hidden behind kPrintTrace flag to avoid
  expensive string interpolations.

* Also, added debugging flag for dumping class hierarchy.

This CL reduces analysis time of Flutter gallery by ~2x.
