[tree-ssa] merge to 20030923

[Richard Henderson <rth at redhat dot com>]

I don't consider this merge entirely successful, but it had been
over a month already, and it was only going to get worse...

(1) The inline parameterization changes from mainline had to be
    reverted, and unit-at-a-time disabled entirely.

    The problem here is that pre-merge, libjava/verify.cc gets
    ~990 calls inlined, and without the above reversion post-merge
    we get ~20000 calls inlined.  Which results in a function of
    some 96000 basic-blocks.  If you have a sufficiently large
    machine (>2GB) this will eventually complete, but...

(2) I couldn't merge Java at all.  The changes for unit-at-a-time
    from mainline conflicted heavily with the gimplification changes
    on the branch.

    I'd appreciate it if someone familiar with this code would help
    figure out what needs doing.  At the same time, it would be 
    really nice if we could get Java using tree_rest_of_compilation.

Before and after test result evaluation follows.

	This is the timeout thing I discussed when tree-eh 
	went in.  Not sure why it passed with the pre- results...
