deps: backport 4af8029 from upstream V8

targos · MylesBorins · commit fa922b9be434 · 2017-11-28T13:07:02.000+09:00
Original commit message: [turbofan] Fix missing lazy deopt in object literals. This adds a missing lazy bailout point when defining data properties with computed property names in object literals. The runtime call to Runtime::kDefineDataPropertyInLiteral can trigger deopts. The necessary bailout ID already exists and is now properly used.
