Other platforms besides ARM64 Windows may also have alignment requirements, e.g. PPC and s390. These requirements may affect both the code pointer field and the size field, and so they each need alignment directives because they are stored in different sections. Since aligning wastes a handful of bytes at most, not making alignment conditional on the platform type seems like a good idea.

This requires honoring the instance size of the object stored in the map for JSObject. To do this, allocation is now split into two instrinsics, one that calculates the base size of the allocated object (%GetAllocationBaseSize) and one that actually allocates (%Allocate). In the process, remove objects.tq, which only existed to contain a macro to fetch the default JSObject map, which is functionality that is now in the JSObject class constructor.

Also insert NestedVariableDeclarations in the preparser if they occur. This should be uncommon enough to not hurt preparser performance.

For the reference types anyref, anyfunc, and nullref, there exist sub-typing rules. The spec says A reference type reftype1 matches a reference type reftype2 if and only if: * Either both reftype1 and reftype2 are the same. * Or reftype1 is nullref. * Or reftype2 is anyref. This CL introduces the type nullref for ref-null, and implements the sub-typing rules in the function-body-decoder. Note that because of the sub-typing check validation performance may regresses. In that case we can optimize the sub-typing check.

This also introduces a {WasmExceptionPackage} class to the object model that acts as an interface for allocating and accessing exceptions that originate from WebAssembly.

The conditional v8 initialization was since then moved back to be unconditional, but the TearDown was never restored. Now we need it for wasm, since during tear down the wasm engine synchronizes on all background compile jobs. Omitting this leads to uses of the disposed platform (see https://crrev.com/c/1429861).
