This bug was found while we were developing our MIPS port of OpenJDK which can be triggered by the test case test/hotspot/jtreg/compiler/c1/Test8004051.java.

- Reproduce:
-----------------------------------------
JDK=/home/fool/fujie/workspace/jdk/build/linux-x86_64-server-release/images/jdk

cd /home/fool/fujie/workspace/jdk/test/hotspot/jtreg

${JDK}/bin/javac ./compiler/c1/Test8004051.java

${JDK}/bin/java \
  -Xcomp \
  -XX:-TieredCompilation \
  -XX:+UnlockDiagnosticVMOptions \
  -XX:-InlineNatives \
  -XX:CompileCommand=quiet \
  -XX:CompileCommand=compileonly,java/lang/invoke/ClassSpecializer.findSpecies \
