Reason for revert: [Sheriff] Layout test changes. Original issue's description: > [debugger] debug-evaluate should not not modify local values. > > Debug evaluate no longer writes back changes to the replicated > context chain to the original after execution. Changes to the > global object or script contexts still stick. Calling functions > that bind to the original context chain also have their expected > side effects. > > As far as I can tell, DevTools is not interested in modifying > local variable values. Modifying global variable values still > works as expected. However, I have not yet removed the old > implementation, but merely keep it behind a flag. > > R=mstarzinger@chromium.org, rossberg@chromium.org > > Committed: https://crrev.com/92caa9b85eefffbef51c67428397951bd2e2c330 > Cr-Commit-Position: refs/heads/master@{#32841} TBR=mstarzinger@chromium.org,rossberg@chromium.org,yangguo@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true Review URL: https://codereview.chromium.org/1526553003 Cr-Commit-Position: refs/heads/master@{#32845}
