Since we allocate raw zone memory for its inputs right behind the Node object anyway, drop the previously OOB-accessed 1-element array within the Node and use address computation to get to the inputs storage. Note that this saves one pointer per Node, except for Nodes with zero inputs, where it uses 1*sizeof(Use) more memory than before.

Two small changes were done as part of the port: - Changes TypedArrayInitializeWithBuffer from a TFS builtin to a macro. It was only called from ConstructByArrayBuffer and this removes the overhead of the TFS call. - Introduces a GetTypedArrayElementsInfo that retrieves both the element size and map. Instead of generating the elements kind switch code ( DispatchTypedArrayByElementsKind) twice, just generate once at the beginning of CreateTypedArray. This reduces overall builtins size by 364 bytes (Mac x64.release) - Before 1364 - TypedArrayInitializeWithBuffer 6468 - CreateTypedArray - After 7468 - CreateTypedArray This also improves performance of TypedArray JSPerf benchmarks (SubarrayNoSpecies, ConstructByArrayBuffer) by 5-8%.

Previously, macros that returned true for "ShouldBeInlined" were only compiled if they were called, which made it impossible to type/semantic check all Torque code (e.g. newly added methods to structs). One might argue that all code should be tested (and thus through inlining compiled), but for prototyping, the skipped compilations were definitely annoying. As part of this change, added a ShouldGenerateExternalCode method to declarables (by default returns !ShouldBeInlined) that makes it possible to suppresses C++ code generation for any method. To support this at the lowest level, a NullOStream classes is added as part of this patch. Finally, added support for generating C++ for passing structs as label parameters to run previously inlined methods through the implementation-visitor for non-inlined compilation.

Vars without initialisers don't need to allocate a VariableProxy, as the proxy expression is not really needed for anything. So, we can special case declaration parsing to look ahead for a '=' (plus a few other cases), and skip the variable proxy allocation if it isn't there. As a side-effect, variables that are only declared but never used are no longer marked is_used, and thus not allocated. This saves on generating dead code.
