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
