## Description
We go through the module `Hasura.Backends.MSSQL.FromIr` and split it into separate self-contained units, which we document.
Note that this PR has a slightly opinionated follow-up PR #3909 .

Fix#3666
### Solution and Design
The module `FromIr` has given rise to:
* `FromIr.Expression`
* `FromIr.Query`
* `FromIr.Delete`
* `FromIr.Insert`
* `FromIr.Update`
* `FromIr.SelectIntoTempTable`
And `Execute.MutationResponse` has become `FromIr.MutationResponse` (after some slight adaptation of types).

Although quite far-reaching, this is a completely mechanical change and should have no observable impact outside the server code.
