    Fix points_to_local_or_readonly_memory_p wrt TARGET_MEM_REF

    TARGET_MEM_REF can be used to offset constant base into a memory object=
 (to
    produce lea instruction).  This confuses
points_to_local_or_readonly_memory_p
    which treats the constant address as a base of the access.

    Bootstrapped/regtsted x86_64-linux, comitted.
