  Log Message:
  -----------
  Improve simple tag query performance by enabling the A-cost query possibilities (#914)

Add better regexp detection and test for most common cases

Add ^!.* as regexp check since we allow that syntax

Optimize OR-queries also in the query optimizer

Change tagNameAndValues to use IN
