Vitaly Buka b7ea298dfd [msan] Don't use TLS slots of noundef args ...

Transformations may strip the attribute from the
argument, e.g. for unused, which will result in
shadow offsets mismatch between caller and
callee.

Stripping noundef for used arguments can be
a problem, as TLS is not going to be set
by caller. However this is not the goal of the
patch and I am not aware if that's even
possible.
