        SI/SFmode literals equally by bit-exact canonicalization into
        CONST_INT RTX internally.  And then, make avoid synthesis if
        such multiple identical canonicalized literals are found in same
        function when optimizing for size.  Finally, for literals where
        synthesis is not possible or has been avoided, re-emit "move"

        a sign or zero extension is only required if the modified field

        targets, don't refer to the temporarily incorrectly extended value
