/* This function, assignRole, is designed as a shorthand for the few lines
 * of code which it contains.  This code is used over and over in the
 * action code for the right sides of many of the productions which are for
 * SQL statements that involves host variables.
 *
 * The purpose of this function is to allow the client code to pass in a pointer
 * and if the pointer is NULL, only then should this function assign the given
 * role to the first Unassigned host variable in TheHostVarRoles.
