[11u] RFR 8214862: assert(proj != __null) at compile.cpp:3251

[Roland Westrelin]

Original bug:
  https://bugs.openjdk.java.net/browse/JDK-8214862
  https://bugs.openjdk.java.net/browse/JDK-8214862
 
Original patch does not apply cleanly to 11u because for a couple of
files (compile.hpp and node.cpp) the code around the changed lines
doesn't strictly match what's recorded in the patch. The resulting
change is otherwise identical to the initial patch.
 
11u webrev:

Testing: x86_64 build, verified new test fails without the patch and
runs fine with it, tier2
 
Thanks,
