In most cases, the language mode can be inferred from the closure and the context. Computing the language mode instead of passing it around simplifies the ICs and will make it possible to go towards lazily allocating feedback vectors. Currently ICs obtain the language mode from the feedback vectors and with lazy feedback allocation we may not always have feedback vectors. Since computing language mode is a bit expensive we want to defer it as far as possible. In Array builtins and other builtins like Reflect.Set we need to force a language mode when setting the properties. To support these cases the SetProperty methods allow the language mode to be overridden when needed. This is a first cl in a series of cls, that will defer the language mode computation further and remove language mode where it is not needed.

This CL fixes two bugs. First, when looking for a free spot while moving elements to the front, the prototype chain was also considered, even though an object at a specific index might have a hole (free spot). Second, when moving an element to the front, we are not allowed to delete it immediately (to preserve semantics when interacting with non-extensible objects). Such an element is then a free spot, but won't be recognised as such. This CL sets that element to undefined after it was moved, to mark it as a free spot.

The function body decoder already tracks reachability and only calls the backend for reachable code. Thus the checks in the TF backend can be skipped. Note that there was already a DCHECK in place that checks whether {SsaEnv::reached()} always returns true. This was to give fuzzers a chance to prove the reachability analysis in the function body decoder wrong. Since this did not happen, we can not remove the {reached()} method from SsaEnv, since it always returned true anyway.

Port 1a3aab51 Original Commit Message: When generating an Assembler, you currently have two choices: Either let the Assembler allocate a growable internal buffer, which is owned by the Assembler. Or provide an externally allocated buffer, which cannot grow. This CL changes this interface to allow providing any implementation of a buffer. The provided buffer can be a view to an externally owned buffer, which still can grow. This will be used to split WebAssembly compilation and code submission. The buffer needs to be able to grow, but cannot be owned by the Assembler because it has to survive until the code is submitted.

It fixes names and const-declarations of simple accessors, and adds a named constructor to make it explicit that an EnumSet should be constructed from an integral value.

With the changes in this patch, it is now possible to add methods to both Torque's class and struct types. As a special case, "constructor" methods are used to initialize the values of classes and structs when they are constructed. The functionality in this patch includes: - The refactoring of class- and struct-handling code to share field and method declaration code between both. - Addition of the "%Allocate" intrinsic that allocates raw bytes to be allocated from the V8 GC's NewSpace heap as the basis for freshly created, initialized class objects. - An implementation of a CallMethodExpression AST node that enables calling methods and constructors, including special handling of passing through the "this" pointer for method calls on structs by reference. The syntax for struct construction using "{}" remains as before, but now calls the struct's matching constructor rather than implicitly initializing the struct fields with the initialization arguments. A new syntax for allocation classes is introduced: "new ClassName{constructor_param1, constructor_param1, ...}", which de-sugars to an %Allocate call followed by a call to the matching constructor. - class constructors can use the "super" keyword to initialize their super class. - If classes and struct do not have a constructor, Torque creates a default constructor for them based on their field declarations, where each field's initial value is assigned to a same-typed parameter to the the default constructor. The default constructor's parameters are in field-declaration order, and for derived classes, the default constructor automatically uses a "super" initialization call to initialize inherited fields. - Class field declarations now automatically create ".field" and ".field=" operators that create CSA-compatible object accessors. - Addition of a no-argument constructor for JSArrays that creates an empty, PACKED_SMI_ELEMENTS JSArray using the machinery added elsewhere in this patch.
