Review request for JDK-8007154: Remove support for u4 MethodParameter flags fields

Hello, please review this simple patch which removes support for class
files with four-byte flags fields in MethodParameters attributes.

Background: the enhanced metadata spec originally specified four-byte
flags fields in MethodParameters attributes.  However, this was later
changed to a two-byte field.

In order to avoid a flag day, I implemented the format change in such a
way that Hotspot recognizes both formats.  This patch removes support
for the older, and now invalid four-byte format.

The Webrev is here:
http://cr.openjdk.java.net/~emc/8007154/

There has been a clean JPRT run, and I am presently running testlist
(aka. everything).  I expect a clear run there too.

Thanks,
Eric
