Patch: minor efficiency improvement in Host

[Tom Tromey <tromey at redhat dot com>]

Andrew got me cvs write access but I'm not comfortable simply
committing stuff yet.  I'd prefer to get "ok"s for things more
complicated than typo fixes.

This patch makes a couple anonymous classes from 'Host' slight more
efficient.  The compiler will already generate fields in an anonymous
class to capture 'final' variables from the method which are used in
the anonymous class body.

Having an explicit field is only needed if it will be modified in the
anonymous class.  Otherwise we're just duplicating things for no benefit.
