Add ErrorMatches/PanicMatches tests for pre-compiled regexp

 - qt.ErrorMatches single-line match `expectedNegateFailure`
 - qt.ErrorMatches multi-line match `expectedNegateFailure`
 - qt.ErrorMatches multi-line match `expectedCheckFailure`
 - qt.PanicMatches single-line match `expectedNegateFailure`
 - qt.PanicMatches multi-line match `expectedNegateFailure`
 - qt.PanicMatches multi-line match `expectedCheckFailure`
