This new option is set to `false` by default. It should be set only in Canonicalizer tests to detect faulty canonicalization patterns. I.e., patterns that prevent the canonicalizer from converging. The canonicalizer should always convergence on such small unit tests that we have in `canonicalize.mlir`.
Two faulty canonicalization patterns were detected and fixed with this change.

Canonicalization for complex.sub adding same numbers. This canonicalization supports the case like complex.sub(complex.add(a, b), b) -> a.

Adding complex value with 0 for real and imaginary part can be ignored.
NOTE: This type of canonicalization can be written in an easy and tidy format using `complex.number` after constant op supports custom attribute.

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.
