SyntaxError: Rest parameter may not have a default initializer
[parser] Fix parse errors for async arrow function edge cases New test262 tests bring up a couple cases with async arrow functions that V8 didn't seem to handle properly; this patch makes those cases errors: - async (...x,) => y -- Rest parameter must be last formal parameter - async (...x = z) => y -- No default value for rest parameter - async (...x, y) => z -- Rest parameter must be last formal parameter Bug: v8:4483, v8:5051 Change-Id: I024d9ba0c854e8e5e75283df2ee53127b1be090d Reviewed-on: https://chromium-review.googlesource.com/496057 Commit-Queue: Daniel Ehrenberg <littledan@chromium.org> Reviewed-by: Adam Klein <adamk@chromium.org> Reviewed-by: Caitlin Potter <caitp@igalia.com> Cr-Commit-Position: refs/heads/master@{#45116} 2017-05-04 22:08:28 +00:00			`*%(basename)s:7: SyntaxError: Rest parameter may not have a default initializer`
