Recent changes like JDK-8325672, JDK-8302670, JDK-8336999 and JDK-8336095 increased the amount of allocations in the 'comp_arena' which might have a negative impact on footprint because memory is only released once the compilation finished. We should revisit this. See discussion here:

"We should probably create a dedicated arena for each Phase, so that the memory can be released after each phase, and re-used properly with the next phase. That could reduce memory footprint."
