This reverts commit 59bbc7a0851b6e0054bb3ed47df0958822f08880.
This exposes an issue breaking the contract of
`applyPatternsAndFoldGreedily` where we "converge" without applying
remaining patterns.
This avoids accidentally reversing the order of constants during successive
application, e.g. when running the canonicalizer. This helps reduce the number
of iterations, and also avoids unnecessary changes to input IR.
Fixes#51892

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.

This revision fixes a bug where an operation would get replaced with
a pre-existing constant that didn't dominate it. This can occur when
a pattern inserts operations to be folded at the beginning of the
constants insertion block. This revision fixes the bug by moving the
existing constant before the replaced operation in such cases. This is
fine because if a constant didn't already exist, a new one would have
been inserted before this operation anyways.
