[8u] RFR: 8161598: Kitchensink fails: assert(nm->insts_contains(original_pc)) failed: original PC must be in nmethod/CompiledMethod

[Kevin Walls]

Hi -

I'd like to get a review of an 8u backport for:

8161598: Kitchensink fails: assert(nm->insts_contains(original_pc)) 
failed: original PC must be in nmethod/CompiledMethod
https://bugs.openjdk.java.net/browse/JDK-8161598

The jdk9 change was: 
http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/ef326749824a

8u webrev: http://cr.openjdk.java.net/~kevinw/8161598/webrev.00/index.html

Much of it does apply automatically, but 8u does not have 
src/cpu/x86/vm/templateInterpreterGenerator_x86.cpp so for the change 
in  TemplateInterpreterGenerator::generate_native_entry() we look at 
src/cpu/x86/vm/templateInterpreter_x86_32.cpp (and _64.cpp).

JPRT build and test went OK.

Thanks!
Kevin
