[cp-patches] Patch: FYI: Fix PR libgcj/20273

[Tom Tromey]

I'm checking this in on the 4.0 branch, the trunk, and Classspath.
Note that the trunk compiler miscompiles LinkedHashMap at the
moment.  This results in crashes.  I'll file this soon.

I put the test case from the PR into Mauve.
The patch is from Michael Koch.  I don't know why, but it has just
been sitting in bugzilla for a while...
