  Run query test suites

  A query test suite must be a subdirectory of suite_dir and contain
  either files with queries in them, or if the suite name looks like
  "values_operator", the files must contain values for the operator
  instead of full queries.

  The query outputs for each suite will be stored in files named
  after their suites and input file names under the output_dir.
