This fixes issue 49099 (http://crbug.com/49099) that makes chromium
crash if a gc is triggered by setting the scopeinfo in CompileLazy. If
this gc triggers code flushing the compiled function could be flushed,
causing the ASSERT(shared->is_compiled()) to fail. By reordering the
two methods we make sure that no allocation happens before the end of
the method.
