Refactor the AllocateAssemblerBuffer helper for the new Assembler API. This is the only non-mechanical part, all other callsites that create Assembler instances can be trivially changed to the new API. This will be done in a separate CL.

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.

Instead of listing all the different combinations of arguments (which is one more now, temporarily), just forward all arguments down via MacroAssembler and TurboAssembler to TurboAssemblerBase. Interestingly, this requires more specific types sometimes (int instead of size_t), since further down the forwarding chain, the compiler does not recognize any more that the value is a constant, and emits a warning about a possibly truncating implicit conversion.

After moving to its own header, this CL cleans up some parts of the interface. 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. Also refactor the use in cctest.h to have less statically declared constants. Instead, just create the set of extensions in the individual tests.

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.

This new method returns no value and just verifies that the Maybe is not Empty. This is intended to be used for functions like Object::Set that return a Maybe<bool> but only use "emptiness" to indicate its result and where ToLocalChecked() appears to be discarding information. Also comments Object::Set to indicate that Check() is the preferred way of asserting that the Set should always succeed.

_xgetbv is reserved for the implementation and shouldn't be used by user code. Newer GCCs and clang trunk define _xgetbv, leading to a name collision if xsaveintrin.h gets included transitively. This unbreaks building v8 with clang trunk and libstdc++ 4.9, which happens to pull in xsaveintrin.h transitively through <algorithm>. Newer versions of libstdc++ don't seem to do that anymore which is why this issue never showed up before.

Storing a VariableProxy in declarations means that a declaration and initialisation assignment are tightly coupled to use the same var. In particular, this means that Var declarations in with scopes have to clone the VariableProxy to split the declaration and initializer LHS lookup. This patch changes declarations to point directly to the Variable, not the VariableProxy. This will allow future refactoring to decouple declarations and initialisations.
