OOM inducing tests need to be filtered from the stress mix candidates

[schaabs]

We are including a number of tests in our stress mixes which induce OOM situations either because of large allocations or because of allocations rooted by static feilds. We need to investigate which tests in our stress mix candidates are at fault for this and filter them from our stress mixes. The following buckets illustrate failures of this nature and can be used as a starting point to identify tests which need to be filtered from the mix.

SIGABRT_System.OutOfMemoryException_libstdc++.so.6!__gnu_cxx::__verbose_terminate_handler
SIGABRT_System.OutOfMemoryException_libcoreclr.so + -1!UNKNOWN
SIGABRT_System.OutOfMemoryException_libcoreclr.so!JIT_New
