Redefine the order of trunc_index, and instantiate it as weak order.

feat(library/class): mark instances as quasireducible by default

quasireducible are also known as lazyreducible.
There is a lot of work to be done.
We still need to revise blast, and add a normalizer for type class
instances. This commit worksaround that by eagerly unfolding
quasireducible.
