Patch: FYI: CNI test directory

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in on the trunk.

This adds support for CNI tests to the libjava test suite.

This patch also adds a couple tests.  One, shortfield, is the test
that Andrew wrote for the old gcj/g++ layout disagreement.  The other,
longfield, shows the current Process bug.
