[please test] RTL sharing verifier

Hi,
as mentioned in previous mail, I would like to get the RTL sharing
verifier enabled in stage1 now. I am however aware that this is likely
going to find many positives, probably more than I can deal with myself
in resonable time. I am attaching my current patch I know to work on
i686 to ask everyone who wants to do little RTL debugging on his
favorite target to try it out and let me know how it works and if
possible also send fixes.
I know the patch fails on PPC-linux on subreg sharing in libjava, but I
didn't had chance to investigate.
Constants, memories and subregs assumed to be shareable are probably the
most common mistakes.
The patch contains the fixes I sent in previous mail plus neccesary
changes to enable the verifier. If this grand plan fails, we can
probably try enabling verifier in the pass queue order and gradually fix
backends.
