Hi all,

could you please review this small fix which introduces a Xcomp-specific problem-list?

the analysis of the failures from last two weeks showed that most of timeouts w/ -Xcomp happen in a handful number of tests. the patch puts the tests which times out only w/ Xcomp.

for the record, here is the statistics on how many timeouts we have observed:
java/lang/invoke/MethodHandles/CatchExceptionTest : 33 times, on different platforms
vmTestbase/vm/mlvm/meth/stress/jni/nativeAndMH : 32 times, only on solaris-sparc 
runtime/appcds/cacheObject/DifferentHeapSizes : 17 times, only on solaris-sparc 
java/lang/Class/forName/modules/TestDriver : 10 times, only on solaris-sparc

Thanks,
