Request for reviews (XXS): 7086560: 7085404 changes broke VM with -XX:-EnableInvokeDynamic

[Vladimir Kozlov]

Thank you, John

I am testing performance regression versus jdk7 b135 which does not have needed 
jsr292 java code so I have to run VM with -XX:-EnableInvokeDynamic, otherwise 
you get next failure:

% gamma -Xcomp t
Using java runtime at: /java/re/jdk/7/promoted/all/b135/binaries/solaris-amd64/jre
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/invoke/MethodHandle

And today I updated my Hotspot sources to latest changeset, rebuild and it 
crashed in ciField()::is_call_site_target().
