    gimple-fold: Recompute ADDR_EXPR flags after folding a TMR [PR98268]

    The gimple verifier picked up that an ADDR_EXPR of a MEM_REF was not
    marked TREE_CONSTANT even though the address was in fact invariant.
    This came from folding a &TARGET_MEM_REF with constant operands to
    a &MEM_REF; &TARGET_MEM_REF is never treated as TREE_CONSTANT
    but &MEM_REF can be.

            recompute_tree_invariant_for_addr_expr after successfully
            folding a TARGET_MEM_REF that occurs inside an ADDR_EXPR.
