Moved qobjectperformance into other/
The qobjectperformance test is a kind of performance test that asserts that the time it takes to emit a signal to a certain number of receivers does not exceed a certain time. other/ currently seems to be a sensible place for such a test. Alternatively, it could have been put next to corelib/kernel/qobject/. Change-Id: I5c9461b62984f5806d1f6940123d30ef9f9f5a37 Reviewed-by: Jason McDonald <jason.mcdonald@nokia.com>
