Hi all,

Please review this backport for the introduction of the StoreLoad barrier into G1's write barrier. The patch from 8 does not apply cleanly to 7u60 since the MacroAssembler code was broken out of assembler*.[ch]pp into macroAssembler*.[ch]pp. When I manually edited the patch file to apply the change to the assembler*- files the patch applies with a line offset so the code has not been changed, just moved. (this fix depends on JDK-8029335, however that change backports cleanly so as per the process no extra code review is required for the backport.)

as far as I can see it looks good.

Thomas
