@inline(__always) does not imply inlinable, which means that it effectively does nothing in the context of the Accelerate overlay. I have replaced all of these with @inlinable where that can be done as a one-line change. Functions that switch over open enums and more complex API (DCT, DFT, FFT) will require more sophisticated corrections, which we can undertake in later commits. For now, they have been rolled back to simply being normal public API.
