This reverts commit 14de196a.

Reason for revert: Tanks Mandreel, fix is in flight, but we want a stable baseline first. Will reland again next week.

Original change's description:
> [turbofan] Handle comparison operations in early lowering.
> 
> This handles relational comparison operations (no equality yet) having
> number feedback during the early type-hint lowering (i.e. during graph
> construction).
