Please review change for JDK-8065402 
<https://bugs.openjdk.java.net/browse/JDK-8065402> - G1 does not expand 
marking stack when mark stack overflow happens during concurrent marking.

I added call to the G1CMMarkStack::expand() from 
G1ConcurrentMark::mark_from_roots().

I added comment and attachment to the JDK-8065402 
<https://bugs.openjdk.java.net/browse/JDK-8065402> with an explanation 
of testing.

Thank you,

Alex
