RFR: 8048214: Linker error when compiling G1SATBCardTableModRefBS after include order changes

[Mikael Gerdin]

Hi all!

A small build issue occurs with the change for 8047818 due to some strange 
include order effects.
The symptom is that a template function in G1SATBCardTableModRefBS is not 
instantiated when compiling on Windows and the link of jvm.dll fails.

Since 8047818 is already reviewed and is a change we want to keep separate I'd 
like to push the fix for this issue before 8047818 instead of folding it into 
that change.

My suggested fix is to move the implementations of the callers of the template 
function into the cpp file as well. They override virtual functions so they 
should not have been inlined in the first place (since we always call through 
a base class pointer to the BarrierSet).
