See the comment added in this commit for details. Currently unused. Would save some IWRAM usage in the matrix implementation at the cost of readability. If one operation on a matrix size is used, most other operations will likely be used too, so in practice this may not change IWRAM usage much. Only including the matrix sizes that are used in the final binary would likely have a greater impact. FURTHER TESTING REQUIRED.
