Generally, I'd expect that we shouldn't be creating .COND_ADD etc. calls for conditional reductions for SCALAR_FLOAT_TYPE_P if !flag_associative_math, but probably also the fold left reduction code needs to either assert it isn't conditional or needs to handle it. E.g. needs_fold_left_reduction_p returns true if it has to do an in-order reduction. But guess Richard will know the details much better.
