to be investigated later
Remove the partially implemented `DoWhileScope` because we don't use it, so no need to specialize the `LoopScope`.
This reverts commit f23ecea.
Those two classes are only used for stree -> sdfg conversion and thus don't belong in `treenodes.py`.

LGTM for now and we will keep the PR comments alive to fix them
The test had an array that was too small since forever. Recent changes on mainline must have made memlet propagation through LoopRegions better.

Description
Schedule trees are an alternative representation of code in DaCe. It is a tree of nodes that represent the execution order of the SDFG. The tree can be used to perform schedule transformations on the SDFG, i.e., erasing an empty
ifbranch, or merging two consecutivefor-loops.A first version of the schedule tree representation was merged with PR #1145, which adds support for creating schedule trees from SDFGs. This PR builds on #1466 and brings a first version of the transformation from schedule tree to SDFG.
