Class fields needs to be initialized after `this` is bound, as per the new spec change: https://github.com/tc39/proposal-class-fields/pull/92 This CL moves the initialization of `this` from parser desugaring to the bytecode generator. Bug: v8:7647 Change-Id: I20f749403e5a4d2f06a39726cf39012ceb541987 Reviewed-on: https://chromium-review.googlesource.com/1014383 Reviewed-by: Mythri Alle <mythria@chromium.org> Commit-Queue: Sathya Gunasekaran <gsathya@chromium.org> Cr-Commit-Position: refs/heads/master@{#52646}
