  Log Message:
  -----------
  Bug 7458: Improve primitive-instance? on known types

* sources/dfmc/llvm-back-end/llvm-emit-computation.dylan
  (emit-primitive-call): Special-case calls to primitive-instance?  to
   invoke do-emit-instance-cmp directly so that better code for checks
   against known types can be generated.

* sources/dfmc/llvm-back-end/llvm-emit-type-check.dylan
  (do-emit-instance-cmp): Add a method specialized on <object-reference>
   that will delegate to one of the other methods based on the
   referenced type object.
