Update to the context for this patch:

I have implemented it's accompanying hotspot patch, JDK-8006949, such
that hotspot will recognize and load *both* kinds of classfiles: those
with u2 flags as well as those with u4.

Therefore, I will push JDK-8006949, and wait for it to propagate from
hsx to tl before pushing this patch.

However, I would still appreciate reviews in the mean time.
