- Dup shuffles broadcast a single lane from a source operand to all lanes of the destination. Conceptually similar to a splat, they require special handling since the splatted value must be extracted from a source. The 32x4 case is already well handled (pshufd) but 16x8 and 8x16 currently generate the general shuffle code sequence. - Adds IA32S16x8Dup, IA32S8x16Dup opcodes.

Remove GetHeaps from String::MakeExternal by first checking the String is not in RO_SPACE (by checking the MemoryChunk's identity) and only then getting the heap from the chunk. Also changes String::CanMakeExternal in api.cc to not use GetHeap. Also remove check GetHeap()->Contains(this/map) that attempts to print INVALID POINTER/INVALID MAP as it's much more likely that the code will crash in either GetHeap or Contains before printing anything.

This extends the Promise#then protector to also guard the intrinsic %ObjectPrototype%, making it usable for fast-path logic in the AsyncGeneratorResolve operation, where we can skip the "then" lookup on the iteratorResult in that case. We also add a corresponding fast- path to the ResolvePromise builtin itself, which avoids the second "then" lookup on the async iterator side. This reduces execution time of the fibonacci-async-es2017-native test from 298.16ms to 280.55ms, which corresponds to an improvement of ~6% in this case. This is a rebased reland of https://chromium-review.googlesource.com/967203 which landed earlier, but had to be reverted as part of the mega-revert that was necessary to fix the async_hooks breakage in Node 10.

This CL completes the implementation of DataView prototype methods in TurboFan, by implementing the Uint8, Int8, Uint16, Int16, Uint32, Int32, Float32 and Float64 setters. DataView performance is now ahead of the equivalent TypedArray wrapper, and is now expected to at least match TypedArray performance in the general case as well. This CL also adds a test file in the compiler directory, to make sure that the setters actually behave correctly.
