[cctest] add Async Generator bytecode tests These were originally written as part of https://chromium-review.googlesource.com/c/550396/. I've separated them out into a separate CL with the intent of landing it first, so that it's easier to see the difference these CLs will have on generated bytecode.

Reland "[async-iteration] implement spec-change to `yield` in async generators" Per https://github.com/tc39/proposal-async-iteration/pull/102/files: AsyncGeneratorResolve no longer unwraps a value component. Instead, the value is unwrapped before the builtin call via Await, allowing Promise rejections to affect the generator control flow. Thus, all `yield <expr>` implicitly become `yield await <expr>`. Additionally, `return <expr>` becomes `return await <expr>`. Finally, when the generator is resumed with `.return()`, the parameter passed to .return() is awaited before generator execution properly continues).

[interpreter] refactor BuildGeneratorSuspend/Resume into BuildSuspendPoint Simplify the model for generating Awaits, because the resume point is always immediately following the suspend point, and registers used are always the same for both operations. Includes a minor refactoring of BytecodeGenerator::VisitYield() to perform iterator result creation before the SuspendGenerator bytecode, rather than between SuspendGenerator and Return. This adds a small number of bytecodes for each yield.

[interpreter] refactor BuildGeneratorSuspend/Resume into BuildSuspendPoint Simplify the model for generating Awaits, because the resume point is always immediately following the suspend point, and registers used are always the same for both operations. Includes a minor refactoring of BytecodeGenerator::VisitYield() to perform iterator result creation before the SuspendGenerator bytecode, rather than between SuspendGenerator and Return. This adds a small number of bytecodes for each yield.

[interpreter] refactor BuildGeneratorSuspend/Resume into BuildSuspendPoint Simplify the model for generating Awaits, because the resume point is always immediately following the suspend point, and registers used are always the same for both operations. Includes a minor refactoring of BytecodeGenerator::VisitYield() to perform iterator result creation before the SuspendGenerator bytecode, rather than between SuspendGenerator and Return. This adds a small number of bytecodes for each yield.

[interpreter] refactor BuildGeneratorSuspend/Resume into BuildSuspendPoint Simplify the model for generating Awaits, because the resume point is always immediately following the suspend point, and registers used are always the same for both operations. Includes a minor refactoring of BytecodeGenerator::VisitYield() to perform iterator result creation before the SuspendGenerator bytecode, rather than between SuspendGenerator and Return. This adds a small number of bytecodes for each yield.

[parser] Provide better error when destructuring callable The patch changes CallPrinter's AST traversal to continue even after the first positive match for an AST node. This helps us check for the subsequent GetIterator AST node in case of destructuring. We can not differentiate between the function call failing and the GetIterator failing based on source position info. This would involve runtime checks costing performance. Instead of providing an incorrect error, we provide both the possiblities to user and allow them to disambiguate.

[interpreter] refactor BuildGeneratorSuspend/Resume into BuildSuspendPoint Simplify the model for generating Awaits, because the resume point is always immediately following the suspend point, and registers used are always the same for both operations. Includes a minor refactoring of BytecodeGenerator::VisitYield() to perform iterator result creation before the SuspendGenerator bytecode, rather than between SuspendGenerator and Return. This adds a small number of bytecodes for each yield.

[generators] remove SuspendFlags enum and related code SuspendFlags was originally used by the suspend operation to determine which field to record the bytecode offset of a suspended generator, and the value the generator was resumed with. For async generators, await operations would use a separate field, in order to preserve the previous yield input value. This was important to ensure `function.sent` continued to function correctly. As function.sent is being retired, this allows the removal of support for that. Given that this was the only real need for SuspendFlags in the first place (with other uses tacked on as a hack), this involves several other changes as well: - Modification of MacroAssembler AssertGeneratorObject. No longer accepts a SuspendFlags parameter to determine which type of check to perform. - Removal of `flags` operand from SuspendGenerator bytecode, and the GeneratorStore js-operator. - Removal of `flags` parameter from ResumeGeneratorTrampoline builtins. - Removal of Runtime functions, interpreter intrinsics and AccessBuilders associated with the [[await_input_or_debug_pos]] field in JSAsyncGeneratorObject, as this field no longer exists. - Addition of a new `Yield` AST node (subclass of Suspend) in order to prevent the need for the other SuspendFlag values.

[generators] remove SuspendFlags enum and related code SuspendFlags was originally used by the suspend operation to determine which field to record the bytecode offset of a suspended generator, and the value the generator was resumed with. For async generators, await operations would use a separate field, in order to preserve the previous yield input value. This was important to ensure `function.sent` continued to function correctly. As function.sent is being retired, this allows the removal of support for that. Given that this was the only real need for SuspendFlags in the first place (with other uses tacked on as a hack), this involves several other changes as well: - Modification of MacroAssembler AssertGeneratorObject. No longer accepts a SuspendFlags parameter to determine which type of check to perform. - Removal of `flags` operand from SuspendGenerator bytecode, and the GeneratorStore js-operator. - Removal of `flags` parameter from ResumeGeneratorTrampoline builtins. - Removal of Runtime functions, interpreter intrinsics and AccessBuilders associated with the [[await_input_or_debug_pos]] field in JSAsyncGeneratorObject, as this field no longer exists. - Addition of a new `Yield` AST node (subclass of Suspend) in order to prevent the need for the other SuspendFlag values.

[parser] Provide better error when destructuring callable The patch changes CallPrinter's AST traversal to continue even after the first positive match for an AST node. This helps us check for the subsequent GetIterator AST node in case of destructuring. We can not differentiate between the function call failing and the GetIterator failing based on source position info. This would involve runtime checks costing performance. Instead of providing an incorrect error, we provide both the possiblities to user and allow them to disambiguate.

[generators] remove SuspendFlags enum and related code SuspendFlags was originally used by the suspend operation to determine which field to record the bytecode offset of a suspended generator, and the value the generator was resumed with. For async generators, await operations would use a separate field, in order to preserve the previous yield input value. This was important to ensure `function.sent` continued to function correctly. As function.sent is being retired, this allows the removal of support for that. Given that this was the only real need for SuspendFlags in the first place (with other uses tacked on as a hack), this involves several other changes as well: - Modification of MacroAssembler AssertGeneratorObject. No longer accepts a SuspendFlags parameter to determine which type of check to perform. - Removal of `flags` operand from SuspendGenerator bytecode, and the GeneratorStore js-operator. - Removal of `flags` parameter from ResumeGeneratorTrampoline builtins. - Removal of Runtime functions, interpreter intrinsics and AccessBuilders associated with the [[await_input_or_debug_pos]] field in JSAsyncGeneratorObject, as this field no longer exists. - Addition of a new `Yield` AST node (subclass of Suspend) in order to prevent the need for the other SuspendFlag values.

[generators] remove SuspendFlags enum and related code SuspendFlags was originally used by the suspend operation to determine which field to record the bytecode offset of a suspended generator, and the value the generator was resumed with. For async generators, await operations would use a separate field, in order to preserve the previous yield input value. This was important to ensure `function.sent` continued to function correctly. As function.sent is being retired, this allows the removal of support for that. Given that this was the only real need for SuspendFlags in the first place (with other uses tacked on as a hack), this involves several other changes as well: - Modification of MacroAssembler AssertGeneratorObject. No longer accepts a SuspendFlags parameter to determine which type of check to perform. - Removal of `flags` operand from SuspendGenerator bytecode, and the GeneratorStore js-operator. - Removal of `flags` parameter from ResumeGeneratorTrampoline builtins. - Removal of Runtime functions, interpreter intrinsics and AccessBuilders associated with the [[await_input_or_debug_pos]] field in JSAsyncGeneratorObject, as this field no longer exists. - Addition of a new `Yield` AST node (subclass of Suspend) in order to prevent the need for the other SuspendFlag values.

This helps us check for the subsequent GetIterator AST node in case of destructuring. We can not differentiate between the function call failing and the GetIterator failing based on source position info. This would involve runtime checks costing performance. Instead of providing an incorrect error, we provide both the possiblities to user and allow them to disambiguate.

[generators] remove SuspendFlags enum and related code SuspendFlags was originally used by the suspend operation to determine which field to record the bytecode offset of a suspended generator, and the value the generator was resumed with. For async generators, await operations would use a separate field, in order to preserve the previous yield input value. This was important to ensure `function.sent` continued to function correctly. As function.sent is being retired, this allows the removal of support for that. Given that this was the only real need for SuspendFlags in the first place (with other uses tacked on as a hack), this involves several other changes as well: - Modification of MacroAssembler AssertGeneratorObject. No longer accepts a SuspendFlags parameter to determine which type of check to perform. - Removal of `flags` operand from SuspendGenerator bytecode, and the GeneratorStore js-operator. - Removal of `flags` parameter from ResumeGeneratorTrampoline builtins. - Removal of Runtime functions, interpreter intrinsics and AccessBuilders associated with the [[await_input_or_debug_pos]] field in JSAsyncGeneratorObject, as this field no longer exists. - Addition of a new `Yield` AST node (subclass of Suspend) in order to prevent the need for the other SuspendFlag values.

[async-await] desugar Await in BytecodeGenerator This includes several changes. From most to least interesting: - No longer implement AwaitExpressions using a do-expression. - Reduces frame-size of async generators by not allocating temporary variables to hold results of Await epxressions. - Streamline and reduce generated bytecodes for Await. - Debugger no longer emits a debug::kCallBreakLocation breakpoint for the JS-builtin call performed for Await, and instead only emits such a breakpoint if the operand of Await is actually a call. - Push fewer parameters to Await* builtins, using the receiver for the first parameter (possible now that the CallRuntime invocation not part of the AST). - Adds a new Await AST node. No new members or anything, but it seemed palatable to avoid having `if (is_await())` in a number of VisitSuspend functions.

Reland "[async-iteration] implement spec-change to `yield` in async generators" Per https://github.com/tc39/proposal-async-iteration/pull/102/files: AsyncGeneratorResolve no longer unwraps a value component. Instead, the value is unwrapped before the builtin call via Await, allowing Promise rejections to affect the generator control flow. Thus, all `yield <expr>` implicitly become `yield await <expr>`. Additionally, `return <expr>` becomes `return await <expr>`. Finally, when the generator is resumed with `.return()`, the parameter passed to .return() is awaited before generator execution properly continues).
