Blink needs %ErrorPrototype% in order to properly set up the inheritance chain from DOMException, as specified in WebIDL: https://heycam.github.io/webidl/#es-DOMException-specialness This patch is similar to commit 5ec1cddc ("Expose %IteratorPrototype% as an intrinsic in the public API"), with the difference that there was no entry for %ErrorPrototype% in any of the mappings in contexts.h.

The ')'-in-parameter checking is not necessary for CompileFunctionInContext. The arguments array is expected to be an array of identifiers, not an array of arbitrary strings that get concatenated. Furthermore, there's no reason to have the .toString() representation look like it came from CreateDynamicFunction(), and in fact inserting line breaks makes it more complicated to map line and column numbers correctly. Overall, the --harmony-function-tostring behavior only makes CompileFunctionInContext worse, so this CL removes it.

Tsan figured out that I called compilation_units_.empty() outside a lock. Original message: This CL adds a new function {InitializeCompilationUnit} to initialize a single compilation unit and not just all compilation units at once. This is necessary for streaming compilation eventually. This also required some refactoring on how the working queue for compilation units works. Previously the synchronization was done with an atomic counter, now it is done with a lock. Note that the code to finish compilation of a module still only works if the working queue gets only empty when all work is done. I plan to change this in a different CL. Since the code would not be tested without streaming compilation, I added an experimental flag and a test to test the new code.

In the original CL I moved an error check backwards, unfortunately behind a vector lookup which should not happen when there is an error. Now I also move the vector lookup backwards. Original message: We stored the size of a function body before we check that these values are valid. This caused a failing DCHECK in the constructor of WireBytesRef which checked for integer overflows. With this CL we check the size of the function body before we create the WireBytesRef.

This is the first step in optimizing Map and Set iterators. This ports all the base functionality including - Set.prototype.entries - Set.prototype.values - %SetPrototypeIterator%.next - Map.prototype.entries - Map.prototype.keys - Map.prototype.values - %MapPrototypeIterator%.next to C++ and removes all the dead code and the previous half JavaScript implementation. The next step is to port core parts to CodeStubAssembler and finally inline the fast-paths into TurboFan directly. The relevant design document is at: https://docs.google.com/document/d/13z1fvRVpe_oEroplXEEX0a3WK94fhXorHjcOMsDmR-8 Most of this work is very similar to how the Array iterator works and we mostly follow the same process for the implementation.

Introduce a stripped down version of UseScratchRegisterScope for ARM and use it inside the assembler and macro-assembler. At the exception of the Call instructions, we now use this scope instead of using the ip register directly. This is inspired from how the ARM64 backend works. In general, the benefit of doing this is we can catch cases where ip is being used both by the caller and by the assembler. But more specifically, TurboFan reserves r9 as an extra scratch register because ip can already be used by the assembler. With this utility, we can isolate the cases in the code generator which need an extra register and potentially fix them, allowing us to give r9 back to the register allocator. This patch uncovered places in the assembler where we were using ip unconditionally when we could have re-used the destination register instead.
