    DeclareKnownConstant - given a constant, value, of, type, create a constant in the GCC
                           symbol table. Note that the name of the constant is not used
                           as _all_ constants are declared in the global scope. The front end
                           deals with scoping rules - here we declare all constants with no names
                           in the global scope. This allows M2SubExp and constant folding routines
                           the liberty of operating with quadruples which all assume constants can
                           always be referenced.

                                If name is nul then we assume we are creating a function
                                type declaration and we ignore names.
