We only use the safe math helpers (CheckedNumeric<T>) in very few places. The headers are huge though, and complex. They are pulled in to 839 of our object files, increasing compilation time. I also find the implicit checks more easy to understand than the complex logic in CheckedNumeric. Thus, this CL removes the safe_math headers and implements bounds checks for the five uses explicitly.

Context::microtask_context can be null after v8::Context::DetachGlobal is called, and that should cancel microtasks that are associated to the detached context. However, there are several callers left without the null check to the microtask queue, and that causes crashes. This CL adds the null check and cancellation as the crash fix.

This changes the syntax for constructing structs and classes to explicitly mention the fieldnames, similar to JavaScript object literals. The fields still have to be listed in the same order as in the struct/class declaration. As in Javascript, {foo: foo} can be abbreviated as {foo}. Example: macro NewJSArray(implicit context: Context)( map: Map, elements: FixedArrayBase): JSArray { return new JSArray{ map, properties_or_hash: kEmptyFixedArray, elements, length: elements.length }; } Drive-by cleanup: Make struct and class constructors follow the same pattern in the parser and the AST.

When TurboFan optimizes field access, we need to check first that the runtime already determined the correct field representation properly.

With lazy feedback allocation we load the interrupt budget from the ClosureFeedbackCellArray instead of the bytecode array. The factory method that constructs the ClosureFeedbackCellArray ensures we have a field for interrupt budget. So, it is safe to omit bounds check here. Including the bounds check increases the size of all jump bytecode handlers by around ~120 bytes. This translates to ~9-10KB of the native code size on Android.

This adds preliminary support for handling the "br_on_exn" opcode in the interpreter. It also makes "catch" and "rethrow" use a proper exception reference instead of a dummy value. To that end this also adds {Handle<>} as a new kind of {WasmValue} which is intended to pass reference values (e.g. "anyref" or "except_ref") to the runtime system. Therefore lifetime of such a {WasmValue} is directly coupled to any surrounding {HandleScope}. For now we just store {Handle<>} directly on the simulated operand stack of the interpreter. This is of course bogus, since the surrounding scope does not outlive the interpreter activation. Decoupling the lifetime of the operand stack from a {HandleScope} will be done in a follow-up CL. As a drive-by this change also implements support for the "ref_null" and the "ref_is_null" opcodes as a proof-of-concept that the new {WasmValue} is also applicable to the "anyref" reference type.

In the process turn the Torque's Arguments type into a real struct and add interoperability with it and CSA's CodeStubArguments. This change is motivated by the desire to include Arguments in structs (e.g. iterators), which is not possible for constexpr fields.
