      Description

      Bisection shows this starts to happen after JDK-8223051. There are many tests failing in tier1. I wonder if 32-bit code dislikes loops with *L nodes now.

      Here is the example failure:

      $ CONF=linux-x86-server-fastdebug make clean images run-test TEST=compiler/c2/TestMatcherLargeOffset.java

      STDOUT:
