Increase the size of the translation cache to keep up with the demands

of running modern large applications:

* the maximum number of sectors is increased from 24 to 48

* the default number of sectors is increased from 16 to 32 on all targets
  except Android

* the default number of sectors is increased from 6 to 12 on Android targets
