Description
Now that https://github.com/JuliaLang/julia/pull/15516 has landed, we should be able to get rid of the generated functions in the Partials code (at least on v0.6 and beyond).
We'll have to make sure that SIMD optimizations still occur, but it should be fine if the new NTuple generators are unrolling the code at compile time.

Research direction
Start by locating the Partials code and the generated functions it uses, then review Julia PR 15516 and the new NTuple generators. Confirm that replacing the generated functions preserves SIMD optimization; the work is done when the Partials implementation no longer depends on those generated functions and its existing behavior and optimization remain intact.
