Both TurboFan and ThinStrings have been enabled by default for a while. This just disentangles the implication between those two flags and sets the --thin-strings individually. There is no technical reason for the implication.

Add the ability for the typer to track whether a string could be the empty string. This is needed for typed lowering of JSStringConcat since we can't create cons string chain with the empty string in arbitrary positions. The ToPrimitiveToString bytecode handler is modified to collect feedback on whether it has ever seen the empty string, which is used by SpeculativeToPrimitiveToString to ensure that the output is non-empty (or depot) which will subsiquently be used to enable inline cons-string creation for the JSStringConcat operator in typed lowering in a subsiquent CL.

ThrowIfHole bytecodes were handled by introducing deopt points to check for a hole. To avoid deopt loops a hole check protector was used to generate control flow if there was a deopt due to a hole. However, the normal control flow version should be as fast as the deopt version in general. The deopt version could potentially consume less compile time but it may not be worth the complexity added. Hence simplifying it to only construct the control flow. Bug: v8:6383 Change-Id: Icace11f7a6e21e64e1cebd104496e3f559bc85f7 Reviewed-on: https://chromium-review.googlesource.com/525573Reviewed-by:

This removes the last remaining dual implications between sets of flags. Support for this was originally added to support multiple subsequent calls to {SetFlagFromString} switching a set of flags on and off. Now that Chrome no longer relies on this behavior we can remove support for this entirely.

Array buffers can now have an allocation that is larger than the actual buffer, such as when WebAssembly guard regions are enabled.

This CL extracts the classes CompilationHelper, InstantiationHelper, and AsyncCompileJob from wasm-module.cc and puts them into module-compiler.{h|cc}. This is necessary to introduce a WasmCompilationManager which is known to the isolate and manages the lifetime of all AsyncCompileJobs. In addition to the mechanical changes of copying the code and splitting class declaration from instantiation, I did the following changes: * I renamed the CompilationHelper to ModuleCompiler. * A finalizer function is passed to the InstantiationHelper as a parameter. * Adjusted UpdateDispatchTable in wasm-module.cc to make it available in wasm-module.h, also with the internal signature. * Duplicate the ResolvePromise/RejectPromise helper functions. I did not rename InstantiationHelper because I could not come up with a good name, and it could benefit from a small special refactoring anyways.

This CL contains a few pieces: - A new mechanism to create "BuiltinContinuation" checkpoints in TurboFan graphs, which--when triggered--swizzle the values in the the FrameState to be parameters to a typically TF-generated builtin that resumes execution to finish the slow-case functionality. - Continuation builtins that have special handling in the deoptimizer and their own new frame type to ensure that the values they need to begin executing can be stashed away and restored immediately before the builtin is called via a trampoline that runs when the continuation builtin's frame execution resumes. - An implementation of Array.prototype.forEach in TurboFan that can be used to inline it. The inlined forEach implementation uses the checkpoints mechanism described above to deopt in the middle of the forEach in the cases that optimization invariants are violated. There is a slightly different continuation stub for each deopt point in the forEach implementation to ensure the correct side-effects, i.e. that the deopt of the builtin isn't programmatically observable.
