rev 6322 : 8038930: G1CodeRootSet::test fails with assert(_num_chunks_handed_out == 0) failed: No elements must have been handed out yet
Summary: The test incorrectly assumed that it had been started with no other previous compilation activity. Fix this by allowing multiple code root free chunk lists, and use one separate from the global one to perform the test.

rev 6324 : 8037344: Use the "next" field to iterate over fine remembered instead of using the hash table
Summary: After changes to the PerRegionTable where all these PRTs are linked together in an additional field, simplify iterating over all PRTs by using these links instead of walki

rev 6329 : 8040792: G1: Memory usage calculation uses sizeof(this) instead of sizeof(classname)
Summary: A few locations in the code use sizeof(this) which returns the size of the pointer instead of sizeof(classname) which returns the size of the sum of its members. This change fixes these errors and adds a few tests.
