[8u] RFA for JDK-8148175: C1: G1 barriers don't preserve FP registers

[David Buck]

Hi!

We have identified a small issue with the testcase (G1 not enabled by 
default in JDK 8). I have asked Mutu, offline, to fix the testcase and 
do one last round of code review.

I am approving this backport on the condition that the testcase is fixed 
and one more round of code review is successfully completed.

Cheers,
-Buck
