adamk	66178c8f53	Remove --harmony-async-await runtime flag ... It shipped with Chrome 55 stable. R=littledan@chromium.org Review-Url: https://codereview.chromium.org/2621173002 Cr-Commit-Position: refs/heads/master@{#42203}	2017-01-10 23:27:02 +00:00
littledan	dcd61b9020	Filter out synthetic variables from with scopes ... This patch ensures that variables like .new_target aren't overwritable using with scopes. It does this by ensuring that scope analysis does not consider with scopes (or eval scopes) for such 'synthetic variables', similarly to how the 'this' variable was already handled. The patch also adds a DCHECK for the dynamic parallel to this case, replacing a previous unreachable path for a particular instance.

littledan	bd078193a0	Remove synthetic unresolved variables from async/await desugaring ... This patch uses temporaries rather than unresolved variables for .promise and .debug_is_active. For .promise, a new field is added to the FunctionState, similarly to .generator_object. This change fixes a bug where .promise was locally shadowable by with, affecting program semantics.
