qtbase/tests/auto/sql/kernel/qsqldatabase/tst_databases.h
Frederik Gladhorn 85a2653737 Enable running sql model tests in parallel 
Each model test gets its own temporary directory, thus there is no problem parallelizing them.

This should reduce the time spent for a testrun of qtbase by around 3 minutes.
When running only the sql tests it saves less since there are no other tests to run in parallel.

=== Timing: =================== TEST RUN COMPLETED! ============================
  Total:                                       4 minutes 43 seconds
  Serial tests:                                4 minutes 42 seconds
  Parallel tests:                              1 second
  Estimated time spent on insignificant tests: (no time)
  Estimated time saved by -j4:                 1 second
=== Totals: 12 tests, 12 passes ================================================
