This patch is not OK, but it's close.

We should not call unshare_expr on DECL_INITIAL until after the
mark_used call, as static data members in templates will not have proper
initializers until after that point.  Also, there's no need to unshare
*before* calling fold_non_dependent_expr.

In fact, there's no need to unshare before the return statement at the
end of the function.  That will avoid creating trees that will only be
thrown away later.

So, why not just do:

return unshare_expr (decl);

at the end of the function?
