pure virtual

Method to try and mark a result as invalid.

When the outer analysis manager detects a change in some underlying unit of the IR, it will call this method on all of the results cached.

This method also receives a set of preserved analyses which can be used to avoid invalidation because the pass which changed the underlying IR took care to update or preserve the analysis result in some way.

Returns
true if the result is indeed invalid (the default).
