[8u] RFR for backport of JDK-8148175: C1: G1 barriers don't preserve FP registers to jdk8u-dev

[Erik Österlund]

Hi Muthusamy,

Looks good. But...

In PreserveFPRegistersTest.java:54
54: long regionSize = 1_000_000; //WB.g1RegionSize();

Was it intentional to hard code the region size to 1 000 000?

Thanks,
/Erik
