Patch: FYI: Merge BC branch to trunk

This patch merges the BC branch to the trunk.  After this patch, I
think the BC branch is dead; I'll submit another patch to update the
web pages.  I've made a tag on the branch at the merge point.

The resulting compiler passes the libgcj test suite.
Tested on x86 FC2.

Most of the new code in the compiler is controlled by the
-findirect-dispatch and -fnew-verifier options.  These don't seem to
have been documented on the branch, but I have a list of minor
documentation updates I'll be making soon, so I will fix these as
well.

The runtime side involves many changes, most notably a complete
reworking of our runtime linking.  It now handles all the [oai]table
stuff mentioned in the GCC Summit paper, and it also is just cleaner
in general.

I'm attaching the patch compressed as it is quite large.
I'm appending the ChangeLog entries as well.  It wasn't clear to me
how to handle these for a merge, so I just put all the entries from
the branch at the top of the existing ChangeLog.

This patch changes Class; you will need to do a clean rebuild of
libgcj.
