RFR 8178949: The split verifier allows anewarray to create an array of more than 255 dimensions.

Hi,

Please review this small JDK-10 fix for anewarray bytecodes that try to 
create arrays with more than 255 dimensions.

JBS Bug:  https://bugs.openjdk.java.net/browse/JDK-8178949

The fix was tested with JCK lang and vm tests, the JTreg hotspot, 
java/io, java/lang, java/util and other tests, the RBT tier2 -tier5 
tests, the co-located NSK tests, and with JPRT.

Thanks, Harold
