Patch: instanceof regression test

[Tom Tromey <tromey at cygnus dot com>]

I'm checking this in.  It adds a simple regression test for the
`instanceof' operator.  (Nothing is wrong with instanceof, but this
test is useful to test some changes I'm playing with.)

	* libjava.lang/instance.out: New file.
	* libjava.lang/instance.java: New file.
