wren romano	c948922567	[mlir][sparse] Factoring out type-based function-name suffixes ... Depends On D115010 This changes a couple of places that used to `return failure();` to now use `llvm_unreachable()` instead. However, `Transforms/Sparsification.cpp` should be doing the necessary type checks to ensure that those cases are in fact unreachable.

wren romano	bc04a47038	[mlir][sparse] adding OverheadType::kIndex ... Depends On D115008 This change opens the way for D115012, and removes some corner cases in `CodegenUtils.cpp`. The `SparseTensorAttrDefs.td` already specifies that we allow `0` bitwidth for the two overhead types and that it is interpreted to mean the architecture's native width.

wren romano	85b8d03e12	[mlir][sparse] Factoring out Transforms/CodegenUtils.{cpp,h} ... This moves a bunch of helper functions from `Transforms/SparseTensorConversion.cpp` into `Transforms/CodegenUtils.{cpp,h}` so that they can be reused by `Transforms/Sparsification.cpp`, etc. See also the dependent D115010 which cleans up some corner cases in this change.
