poly_int: current_vector_size and TARGET_AUTOVECTORIZE_VECTOR_SIZES
This patch changes the type of current_vector_size to poly_uint64.
It also changes TARGET_AUTOVECTORIZE_VECTOR_SIZES so that it fills
in a vector of possible sizes (as poly_uint64s) instead of returning
a bitmask. The documentation claimed that the hook didn't need to
include the default vector size (returned by preferred_simd_mode),
but that wasn't consistent with the omp-low.c usage.
