The JDK-8058176 introduces code cache size monitoring mechanism, to never allow code cache exhaustion during mlvm stress tests' work.

In case of segmented code cache, MH linkers built in mlvm's MHTransformerGen class, go to nmethods heap. If JDK-8263377 (placing them to the non-nmethods heap) got implemented, the code cache size monitoring in the MHTransformerGen should be adjusted to not monitor nmethod pools.
