    tree-optimization/106403 - fix ICE with VN of .STORE_LANES

    While .STORE_LANES is not supported by the recent VN patch we were
    still accessing the stored value and valueizing it - but
    internal_fn_stored_value_index does not support .STORE_LANES and
    we failed to honor that case.  Fixed by simply moving the affected
    code below the check for the actual supported internal functions.

            * tree-ssa-sccvn.cc (vn_reference_lookup_3): Move stored
            value valueization after check for IFN_MASKED_STORE or
            IFN_LEN_STORE.
