Detailed Description

Splits flattened maps into nested maps along the divisions of their induction variables.

Applies transformations::MapDelinearize wherever it can, so that accesses like A[64*idiv(i, 256) + imod(i, 64)], which reshapes and fusing nests of different shapes leave behind, become affine in the induction variables of a nest again.
