`self` clauses on compute constructs take an optional condition expression. We again limit the implementation to ONLY compute constructs to ensure we get all the rules correct for others. However, this one will be particularly complicated, as it takes a `var-list` for `update`, so when we get to that construct/clause combination, we need to do that as well. This patch also furthers uses of the `OpenACCClauses.def` as it became useful while implementing this (as well as some other minor refactors as I went through). Finally, `self` and `if` clauses have an interaction with each other, if an `if` clause evaluates to `true`, the `self` clause has no effect. While this is intended and can be used 'meaningfully', we are warning on this with a very granular warning, so that this edge case will be noticed by newer users, but can be disabled trivially.
