  [MC] Remove SetUsed on isUndefined and getFragment

Due to the known limitations of .set reassignment (see
https://sourceware.org/PR288), we use diagnostics to reject patterns
that could lead to errors (ae7ac010594f693fdf7b3ab879e196428d961e75 2009-06)).

This code gets refined multiple times, see:

* 9b4a824217f1fe23f83045afe7521acb791bc2d0 (2010-05) `IsUsedInExpr`
* 46c79ef1132607aead144dfda0f26aa8b065214f (2010-11) renamed `IsUsedInExpr` to `IsUsed`

The related `SetUsed` bit seems unnecessary nowadays.
