This adds support for lowering {JSCreateArguments} within outermost frames of type {CreateArgumentsType::kMappedArguments}. It will hence enable escape analysis to work with such objects and allow for further optimization. This also adds a new {NewMappedArgumentsElements} simplfied operator. Note that escape analysis support for this new operator will be done as a follow-up.

This adds an initial implementation of the DeserializeLazy builtin and runtime function, as well as --lazy-deserialization and --trace-lazy-deserialization feature flags. Since lazy deserialization itself isn't implemented yet, DeserializeLazy simply replaces itself with the appropriate builtin. The builtin_id is loaded from the SFI, and the builtin itself is loaded from the Builtins table.

... for AbstractValue and AbstractControl. This allows to access the fields directly instead of via {interface_data}, and hence makes the code more readable. Also, it makes AbstractValue and AbstractControl non-templates. They are also renamed to ValueBase and ControlBase. Unfortunately, it requires the introduction of new templates ValueWithNamedConstructors and ControlWithNamedConstructors, in order to provide correctly typed named constructors (we cannot define implicit conversion from {Value,Control}Base to a subtype because of our style guide, checked by a presubmit check).

Use int instead of byte to store the source position when computing a location based on the stack trace stored in an error object. Also add tests, since this code path was not covered before (not even for small position where it would have succeeded). Also, add some comments about which positions are 0-based and 1-based.

These new tests are somewhat similar to the existing gap resolver tests except we use the code generator and eventually run the generated code. The main idea is to cover cases that are difficult to hit, such as move from/to slots which are out of range of loads and stores, but may happen nonetheless. At this time, the tests only make sure the code generator actually generated some code, and that this code runs. In the future, it would be great to also check that the moves were actually performed.

When calling Object(value) where the value is known to be a JSReceiver, we can just replace it with value, as the Object constructor call is a no-op in that case. Otherwise when value is known to be not null or undefined then we can replace the Object constructor call with an invocation of ToObject. This covers the common pattern found in bundles generated by Webpack, where the Object constructor is used to call imported functions, i.e. Object(module.foo)(1, 2, 3) There's a lot of detail in https://github.com/webpack/webpack/issues/5600 on this matter and why this pattern was chosen.

This patch introduces a new container type ScriptOrModule which provides the name and the host defined options of the script/module. This patch also introduces a new PrimitivesArray that can hold Primitive values, which the embedder can use to store metadata. The HostDefinedOptions is passed to V8 through the ScriptOrigin, and passed back to the embedder through HostImportModuleDynamically for module loading.
