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.

Krzysztof Drewniak 121aab84d1 [MLIR][Affine] Simplify nested modulo operations when able
It is the case that, for all positive a and b such that b divides a
(e mod (a * b)) mod b = e mod b. For example, ((d0 mod 35) mod 5) can
be simplified to (d0 mod 5), but ((d0 mod 35) mod 4) cannot be simplified
further (x = 36 is a counterexample).

This change enables more complex simplifications. For example,
((d0 * 72 + d1) mod 144) mod 9 can now simplify to (d0 * 72 + d1) mod 9
and thus to d1 mod 9. Expressions with chained modulus operators are
reasonably common in tensor applications, and this change _should_
improve code generation for such expressions.

Sumesh Udayakumaran 24b0df8686 [NFC][MLIR] Split large fusion test file into 4 test files
mlir/test/transforms/loop-fusion.mlir is too big and is split into mlir/test/transforms/loop-fusion.mlir,  mlir/test/transforms/loop-fusion-2.mlir, mlir/test/transforms/loop-fusion-3.mlir
and mlir/test/transforms/loop-fusion-4.mlir. Further tests can be added in mlir/test/transforms/loop-fusion-4.mlir
