/* When inserting something into the top bit of a 32-bit structure,

   we must make sure that the register remains properly sign-extended.

   There are two ways of doing this:

     - use purely 32-bit bit manipulations (a single INS, matched twice here).

     - use a 64-bit bit manipulation (DINS), and sign-extend the result.  We

     check for this extension using SLL.  */
