  * long as the prefix is pos/neg.
  *
  * Each testDir can also have a __defaultFlags.flags file, which provides
  * compiler flags and is used unless there's a specific flags file (e.g. for
  * test pos/A.scala, if there's a pos/A.flags file those flags are used,
  * otherwise pos/__defaultFlags.flags are used if the file exists).
