Original bug:
  https://bugs.openjdk.java.net/browse/JDK-8188133

Original fix:
  http://hg.openjdk.java.net/jdk/jdk/rev/d620a4a1d5ed

The patch does not apply to 11u cleanly due to a different patch context in bytecodeInfo.cpp. The
changed lines in the patch itself seem to be the same as the original.

11u webrev:
  http://cr.openjdk.java.net/~shade/8188133/wevrev.11u.01/

Testing: benchmark from the bug, tier1
