In partial template instantiations the expression may not evaluate to a
constant yet because it depends on another template parameter. We cannot set
`PermExpr` to nullptr because we need to preserve the expression to be
evaluated at another call to `ActOnOpenMPPermutationClause` when the template
is fully instantiated.
