[8u-dev] RFA: 8166742: SIGFPE in C2 Loop IV elimination

[David Buck]

Hi!

Please approve the backport of this trivial fix to 8u-dev. The JDK 9 
patch applies cleanly as-is to the 8u-dev forest.

bug report:
https://bugs.openjdk.java.net/browse/JDK-8166742

jdk 9 changeset:
http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/6214eb051a30

jdk 9 review thread:
http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2016-September/024517.html

I have manually tested the fix with the testcase included in the 
changeset. Default and hotspot jprt testsets also run and passed.

Cheers,
-Buck
