  -----------
  [NFC][SimplifyCFG] Rename statistic NumSinkCommons into NumSinkCommonInstrs

It really counts instructions added into common block,
not number of instruction groups sunk.

  [NFC][SimplifyCFG] SinkCommonCodeFromPredecessors(): early return if nothing to sink

If we can't sink even one instruction, early return, to increase readability.

  [NFC][SimplifyCFG] SinkCommonCodeFromPredecessors(): count number of instruction "blocks" actually sunk

Out of all the times the function was called,
how many times did we actually sink anything?

I.e. out of all the times HoistThenElseCodeToIf() was called,
how many times did it actually hoist something?
