7143511: G1: Another instance of high GC Worker Other time (50ms)
Summary: Tiered compilation has increased the number of nmethods in the code cache. \
This has, in turn, significantly increased the number of marked nmethods processed \
during the StrongRootsScope destructor. Create a specialized version of \
CodeBlobToOopClosure for G1 which places only those nmethods that contain pointers \
                into the collection set on to the marked nmethods list.
