There are wasm tests which are supposed to fail, but they fail for the wrong reason (because blocks do not declare their type). This CL fixes this, and changes the error output to contain the expected and observed results for better debuggability.

In many cases, this is performance neutral because we can fall off the JavaScript monomorphic fast path for the hash lookup. Once we store the hash code in known fixed position, this should get much faster.

Goal of this CL: explicit return from non-async function has position after return expression as return position (will unblock [1]). BytecodeArrayBuilder has SetStatementPosition and SetExpressionPosition methods. If one of these methods is called then next generated bytecode will get passed position. It's general treatment for most cases. Unfortunately it doesn't work for Returns: - debugger requires source positions exactly on kReturn bytecode in stepping implementation, - BytecodeGenerator::BuildReturn and BytecodeGenerator::BuildAsyncReturn generates more then one bytecode and general solution will put return position on first generated bytecode, - it's not easy to split BuildReturn function into two parts to allow something like following in BytecodeGenerator::VisitReturnStatement since generated bytecodes are actually controlled by execution_control(). ..->BuildReturnPrologue(); ..->SetReturnPosition(stmt); ..->Return(); In this CL we pass ReturnStatement through ExecutionControl and use it for position when we emit return bytecode right here. So this CL only will improve return position for returns inside of non-async functions, I'll address async functions later.

Changes the ShouldUseFullCodegen to use the flags on the literal instead of the SharedFunctionInfo. Also moves the setting of the SFI flags based on the literal to be in the final stage of unoptimized compilation since they are no longer needed on the SFI during compilation. This is in preparation to enable shared function infos to be created after bytecode generation (to enable off-thread bytecode generation).

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.

Returning a double from ToFloat64 could lead to problems. If value_ has the bit representation of a signaling NaN (sNaN), then returning it as double can cause the signaling bit to flip, and value_ is returned as a quiet NaN (qNaN). The usage of the Double wrapper also, makes the function ToFloat64AsInt redundant, since the Double wrapper already has the AsUint64() method, which returns an uint64_t.

In gn, strict aliasing is disabled anyway. Enabling it for gyp can cause the compilation to fail on bots that still use gyp, or (even worse) can lead to miscompilation because the compiler exploits strict aliasing assumptions.

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.
