Michael and I have discussed this offilne, and I think that more
quantitative information here would be helpful. One phrasing might be:
For a reasonable test suite of programs, for the loops we might
optimize, how many different loop-nest variants do we need to represent
for costing purposes (also note that, depending on profiling inf...

...ng
transformations, I think organizing the transformations in code is
sufficient at the beginning. Since transformations apply on subtrees, are
prioritized, and can add candidates to be selected by a cost function, a
pass manager has to be structured differently.

> There are multiple ways regions in MLIR can be viewed, but the more relevant point here is you do have a loop tree structure native in the IR with MLIR. Regions in MLIR didn't evolve from modeling inlined calls - the affine.for/affine.if were originally the only two operations in MLIR
