Disable factoring of constant values during ANALYZE. This is a temporary

fix for [forum:/forumpost/07de5f6216|forum post 07de5f6216].  The register
allocation logic in ANALYZE needs to be completely refactored, but that will
take longer.  This check-in will serve to resolve the issue until a better
fix can be devised.
