I think you need to build a new PAREN_EXPR in the assoc barrier case as
well, for it to have any effect in templates.
My intent was to ignore __builtin_assoc_barrier in templates / constexpr
evaluation since it's not affected by -fassociative-math anyway. Or do you
mean something else?
I agree about constexpr, but why wouldn't template instantiations be
affected by -fassociative-math like any other function?
