poly_int: GET_MODE_NUNITS
This patch changes GET_MODE_NUNITS from unsigned char
to poly_uint16, although it remains a macro when compiling
target code with NUM_POLY_INT_COEFFS == 1.
We can handle permuted loads and stores for variable nunits if
the number of statements is a power of 2, but not otherwise.
The to_constant call in make_vector_type goes away in a later patch.
