[15/n] Consider building nodes from scalars in vect_slp_analyze_node_operations

If the statements in an SLP node aren't similar enough to be vectorised, or aren't something the vectoriser has code to handle, the BB vectoriser tries building the vector from scalars instead. This patch does the same thing if we're able to build a viable-looking tree but fail later during the an
