Hi,

If the default GC is serial/parallel/cms, TestLoopMiningArguments.java
fails. This test check UseCountedLoopSafepoints and
LoopStripMiningIter of default GC. UseCountedLoopSafepoints is false
by default and set true by epsilon/shenandoah/z/g1. When default GC is
not one of these, the test fails. I am not sure why the test requires
one of these particular GCs is by default. I just removed the test of
default GC (testDefaultGC).
