Delete tests in org.eclipse.core.tests.resources #525

In this commit, the deactivated performance tests "_testPerformanceManyResources()"  and "_testPerformanceOneResource()" from MarkerTest.java in org.eclipse.core.tests.resources are deleted because they are not real test methods but rather used for code measuring and printing the time for processing operations on markers. See also #605 (comment). Contributes to #525
