Fixes a stack overflow when traversing particularly deep graphs. This changes the iteration order which changes some of the diagnostic notes, but the diagnostics are still correct and deterministic so it does not matter. Fixed: chromium:47418 Change-Id: I2def633b6d96d1525027f7929b0fa0a6fba0efeb Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/90140 Auto-Submit: James Price <jrprice@google.com> Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Ben Clayton <bclayton@google.com>
