I'm changing SB-C::*POLICY* from a list to a struct. (This yields us a nice compile-file speedup.)

Instead of accessing the global policy with (CDR (ASSOC ...)) it should be accessed with (SB-C::POLICY-QUALITY) as per the attached diff.

This function has been present since 2000-12-29 and the interface is unchanged, so a new ASDF can work just fine with an older SBCL. The reverse is not possible. I'll patch the ASDF that ships with SBCL.
