Subject: fix x86 darwin

This fixes the builds on x86 darwin. They've been broken since:

2004-06-08 Zdenek Dvorak <rakdver@atrey.karlin.mff.cuni.cz>

        PR rtl-optimization/15717
        * config/i386/i386.c (legitimate_constant_p): Do not allow
        x - symbol_ref.

I developed my own version, and then I found Andrew had a version, while investigating, I found Stuart had a patch to fix a recent breakage introduced by Mark in the great darwin.c rewrite. I folded all the aspects of them together and ended up with the below...

Bootstrapped on i686-apple-darwin8.0.0b1.
