When compiling runtime, we don't allow closures to escape, because we don't want (implicit) allocations to occur when it is not okay to allocate (e.g. in the allocator itself). However, for go statement, it already allocates a new goroutine anyway. It is okay to allocate the closure. Allow it. Also include the closure's name when reporting error. Updates #40724.
