Review Request: Regression Zero fails to handle fast_aldc and fast_aldc_w in hs20

[Xerxes Rånby]

Hi

hs20 uses two new internal instructions fast_aldc and fast_aldc_w.
see: openjdk/hotspot/src/share/vm/interpreter/bytecodes.hpp

This webrev fix by backporting Zero fixes from OpenJDK bug 7032458 and 7030207.
http://labb.zafena.se/openjdk/pr696-zero-fast_aldc-and-fast_aldc_w-regression-hs20/

The webrev are made against hsx20
http://hg.openjdk.java.net/hsx/hsx20/master/

I don't have a bug id for this.

Cheers
Xerxes
