HotSpotResolvedObjectType: implement hasFinalizeSubclass() correctly
don't use the (wrong) cached value, but ask the runtime on each request.
Fixes regression on xml.* benchmarks @ specjvm2008. The problem was:
After the constructor of Object was deoptimized due to an assumption violation,
it was recompiled again after some time. However, on recompilation, the value
of hasFinalizeSubclass for the class was not updated and it was compiled again
with a, now wrong, assumption, which then triggers deoptimization again.
This was repeated until it hit the recompilation limit (defined by
PerMethodRecompilationCutoff), and therefore only executed by the interpreter
from now on, causing the performance regression.
