    tree-optimization/96974 - avoid ICE by replacing assert with standard
failure

    Minor patch to add a graceful exit in the rare case where an invalid
    combination of TYPE_VECTOR_SUBPARTS for nunits_vectype and
    *stmt_vectype_out is reached in vect_get_vector_types_for_stmt.

    This resolves the ICE seen in PR tree-optimization/96974, however the i=
ssue
    of correctly handling this rare vectorization combination is left for a
    later patch.

    Bootstrapped and reg-tested on aarch64-linux-gnu.
