Detailed Description

An abstract set of preserved analyses following a transformation pass run.

When a transformation pass is run, it can return a set of analyses whose results were preserved by that transformation. The default set is "none", and preserving analyses must be done explicitly.

There is also an explicit all state which can be used (for example) when the IR is not mutated at all.
