This is resurrecting an optimization from the pre-torque version. Avoid allocating another sequential string for the result when there's only one element, just return the ToString-ed element. This not only saves time writing to this destination string, but also reduce GC pressure. The System Health Memory Benchmark (load:media:google_images) exposed this missing optimization with a 15% regression in memory usage. Very large external strings were being copied into V8's heap as sequential string.

The relocation mode in question was by now only used in tests to model a wrapper call from wrapper code (on the GC'ed heap) to a non-movable wasm code object. Instead of using a special relocation mode, we switch to using the existing {EXTERNAL_REFERENCE} mode similar to other static C++ functions called from generated code.

This introduces a new syntax for identifiers and calls: modulename::foo. Such a name is resolved by trying to find a module modulename in one of the parent scopes and looking for foo there. So this roughly corresponds to C++ qualified namespace lookup.

No longer use inheritance to associate Torque-generated assemblers with corresponding CSA subclasses. Instead, all references to CSA and CSA-derived assemblers are now explicitly qualified, by generating a short-lived assembler instance in-place. As a consequence, Torque files have to mention the assembler external macros live in. The CodeStubAssembler is the default for this and can be omitted. As a drive-by cleanup, also distinguish between names that are emitted in C++ and names that are intended to be read in error messages. This is relevant for generic instantiations, where the generated names are rather unreadably mangled. As a follow-up, it will be easy to allow for qualified access to different modules, thus implementing full namespace semantics for modules.

The fast paths for sets and maps did not support allocation in large object space, yet they were taken in these cases. This CL adds support, simply by passing the kAllowLargeObjectAllocation argument to AllocateJSArray. It also changes the fast path for strings to use this argument rather than take the slow path.

- Name lookup in module scopes has namespace semantics now: All overloads from all parent modules are combined before overload resolution. - Allow overloads of different callables: runtime-functions, macros, builtins, and generics. - The duplication between the DeclarationVisitor and the ImplementationVisitor is removed: The DeclarationVisitor creates declarables for everything except for implicit generic specializations. The ImplementationVisitor iterates over declarables. The DeclarationVisitor only looks at the header of declarations, not at the body. - Modules become Declarable's, which will enable them to be nested. - Modules replace the existing Scope chain mechanism, which will make it easier to inline macros. - The DeclarationVisitor and Declarations become stateless. All state is moved to contextual variables and the GlobalContext. - Implicit specializations are created directly from the ImplementationVisitor. This will enable template parameter inference. - As a consequence, the list of all builtins is only available after the ImplementationVisitor has run. Thus GenerateBuiltinDefinitions has to move to the ImplementationVisitor. Also, this makes it necessary to resolve the link from function pointer types to example builtins only at this point.

I will enable /Zc:DllexportInlines- flags for faster build time on windows. But the flag makes clang's -Wundefined-inline check more strict as a secondary effect. Actually, having inline function specifier for the function not defined in header file seems bit strange. Let me remove inline specifier from such functions.
