- Address TODO in scf-bufferize: the argument materialization issue is now fixed and the code is now in Transforms/Bufferize.cpp - Tighten up finalizing-bufferize to avoid creating invalid IR when operand types potentially change - Tidy up the testing of func-bufferize, and move appropriate tests to a new finalizing-bufferize.mlir - The new stricter checking in finalizing-bufferize revealed that we needed a DimOp conversion pattern (found when integrating into npcomp). Previously, the converion infrastructure was blindly changing the operand type during finalization, which happened to work due to DimOp's tensor/memref polymorphism, but is generally not encouraged (the new pattern is the way to tell the conversion infrastructure that it is legal to change that type).
