Without checking performance, I think the definition should be moved to g1CollectedHeap.inline.hpp, not the .cpp file (and includes fixed up).

It's used on every reference for a few operations.

[Hamlin-Li]

Thanks Thomas.

Not sure if this method be inlined in original code, but I inline it anyway as you suggested.

[kstefanj]

A lot of the changes to include g1CollectedHeap.inline.hpp look strange to me, are they really needed? And the normal hpp-files that now include it are wrong, we should never have normal hpp-files including inline.hpp-files.

[Hamlin-Li]

Thanks Stefan, I remove the unnecessary inline includes.

[tschatzl]

Lgtm.
