stdlib: Reorder JOIN to be same order as INDEX

Reorder the sequence in which columns are matched during JOINs to be the
same as the order in which the columns are INDEX-ed in the LUTs. This
ensures that every column in the JOIN ON clause is index-able.

Wattson_dsu_pmu: 14509.02 -> 14995.40

Wattson_static_curve_selection: 39375.36 -> 25309.91

Wattson_total_raven_calc: 39600.95 -> 33329.40
