 Fix trac #10647: Notice about lack of SIMD support

 Fixes #10647. Changes the error message when a SIMD size
 variable is required in the native code generation backend.

 Test Plan:
 Try compiling the test case given in the ticket :

 {-# LANGUAGE MagicHash #-}
 module Foo where
 import GHC.Prim
 data V = V Int8X16#

 GHC should give a clearer error message
