River Riddle fb35cd3baf [mlir][NFC] Update textual references of `func` to `func.func` in SparseTensor tests 
The special case parsing of `func` operations is being removed.

Aart Bik 34381a76c1 [mlir][sparse] avoid some codeup in sparsification transformation 
A very small refactoring, but a big impact on tests that expect an exact order.
This revision fixes the tests, but also makes them less brittle for similar
minor changes in the future!

Matthias Springer ab47418df6 [mlir][bufferize] Merge tensor-constant-bufferize into arith-bufferize 
The bufferization of arith.constant ops is also switched over to BufferizableOpInterface-based bufferization. The old implementation is deleted. Both implementations utilize GlobalCreator, now renamed to just `getGlobalFor`.

GlobalCreator no longer maintains a set of all created allocations to avoid duplicate allocations of the same constant. Instead, `getGlobalFor` scans the module to see if there is already a global allocation with the same constant value.

For compatibility reasons, it is still possible to create a pass that bufferizes only `arith.constant`. This pass (createConstantBufferizePass) could be deleted once all users were switched over to One-Shot bufferization.

Mogball a54f4eae0e [MLIR] Replace std ops with arith dialect ops 
Precursor: https://reviews.llvm.org/D110200

Removed redundant ops from the standard dialect that were moved to the
`arith` or `math` dialects.

Renamed all instances of operations in the codebase and in tests.

Aart Bik 68ac2e53ff [mlir][sparse] replace linalg.copy with memref.copy

for a bugfix in the memref copy library in order for
all sparse integration tests to pass.

Aart Bik c194b49c9c [mlir][sparse] add full dimension ordering support 
This revision completes the "dimension ordering" feature
of sparse tensor types that enables the programmer to
define a preferred order on dimension access (other than
the default left-to-right order). This enables e.g. selection
of column-major over row-major storage for sparse matrices,
but generalized to any rank, as in:

dimOrdering = affine_map<(i,j,k,l,m,n,o,p) -> (p,o,j,k,i,l,m,n)>
