Multiply, DCT and FFT have helper instruction options which make REMAP
easier to use.

There are four types of REMAP:
* **Matrix**, also known as 2D and 3D reshaping, can perform in-place
Parallel Reduction instructions, because their Architectural State cannot
hold the partial results).

## Basic principle
The following illustrates why REMAP was added.
