[8u] RFA: 8162540: Crash in C2 escape analysis with assert: "node should be registered"

[Vladimir Ivanov]

Hi,

I'd like to request approval to push a backport of JDK-8162540 into 8u-dev:

   JBS: https://bugs.openjdk.java.net/browse/JDK-8162540

   9 changeset: http://hg.openjdk.java.net/jdk9/jdk9/hotspot
/rev/82e3a58aca6f

   8u webrev: http://cr.openjdk.java.net/~vlivanov/8162540/webrev.00/

   8u review: 
http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2018-May/028994.html

It was fixed back in 9 long time ago, but hasn't been backported yet. 
Recently it was reported that the bug causes incorrect code being 
generated by C2. The fix didn't apply cleanly, but minor adjustments 
were enough.

Thanks!

Best regards,
Vladimir Ivanov
