Subject: [PATCH] X86: Make shift instructions set some of the flags they're
 supposed to. The flag mechanism for microops needs to be fleshd out a little
 more to allow for custom flag calculation methods for certain microops. Shift
 is an example where the rules for calculating OF and CF are unique.
