[8u] RFA 8077420: Build failure with SS12u4

[David Buck]

Hi!

Please approve the backport of the following fix from JDK 9 to 8u-dev:

bug report:
https://bugs.openjdk.java.net/browse/JDK-8077420

JDK 9 code review thread:
http://mail.openjdk.java.net/pipermail/hotspot-dev/2015-April/017930.html

JDK 9 changeset:
http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/4b1c654a2c53

The change applies cleanly to 8u-dev. JPRT run and hotspot testset 
passes with current compilers. Efficacy of fix manually confirmed by 
building with SS 12.4 (C++ 5.13).

Cheers,
-Buck
