fix(library/algebra/order): decidable_linear_order
...
Add fields for decidable_eq and decidable_le.
We need this because a concrete instance may have its own
implementation that is not definitionally equal to
the old ones defined at library/algebra/order.lean.
Without this change, types such as nat and int would
have multiple definitions for decidable_eq and decidable_le
which are not definitionally equal.
