TEST_BUG: gc/6581734/Test6581734.java fails with collectors other than CMS

gc/6581734/Test6581734.java

explicitly specifies -XX:+UseConcMarkSweepGC flag:

@run main/othervm -Xmx512m -verbose:gc -XX:+UseConcMarkSweepGC Test6581734

The test fails when other GC command line flags, such as -XX:+UseParallelGC, are used globally in promotion testing:

----------System.err:(3/222)----------
