This invariant will save us some head ache. The changes to test-debug/DebugStub is due to the fact that it abuses the ability to set break points in code that has no debug break slots. This is now no longer possible. R=ulan@chromium.org BUG=v8:4132 LOG=N Review URL: https://codereview.chromium.org/1181013007 Cr-Commit-Position: refs/heads/master@{#29038}
