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!

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.

68ac2e53ff [mlir][sparse] replace linalg.copy with memref.copy
Note, this revision relies on the following revision
for a bugfix in the memref copy library in order for
all sparse integration tests to pass.

96a23911f6 [mlir][sparse] complete migration to sparse tensor type
A very elaborate, but also very fun revision because all
puzzle pieces are finally "falling in place".

1. replaces lingalg annotations + flags with proper sparse tensor types
2. add rigorous verification on sparse tensor type and sparse primitives
3. removes glue and clutter on opaque pointers in favor of sparse tensor types
4. migrates all tests to use sparse tensor types

NOTE: next CL will remove *all* obsoleted sparse code in Linalg

a2c9d4bb04 [mlir][sparse] Introduce proper sparsification passes
This revision migrates more code from Linalg into the new permanent home of
SparseTensor. It replaces the test passes with proper compiler passes.

NOTE: the actual removal of the last glue and clutter in Linalg will follow
