This unifies the code between parser and preparser, and removes more code from the pattern rewriter. This makes "var x" without assignment and initializer in a loop pessimistically marked as assigned, but that seems pretty unlikely since the variable will just always be undefined. It is also still strictly better than what we had until very recently since any var outside of the function scope used to be marked as assigned. Now we only mark such variables as assigned.

This change makes it less likely to pick one of the registers that are not byte addressable on ia32. This is not a correctness issue but fixes some code size and runtime regressions. After the change to prefer registers that are not used in hinting, it was very likely that one of the registers that are not byte addressable was chosen, leading to extra code in cases where the carry flags was materialized as a real boolean value. With this change, we pick the first register that is not used in hinting, thereby mostly using byte addressable registers on ia32.

Leszek Swirski authored
For desrtucturing assignments from null/undefined, we throw an error that references the destructuring object literal's property name, e.g. for var { x } = null; we report that we cannot destructure 'x' from null. Rather than calculating this property during bytecode generation (and including it in the bytecode as an argument to the type error constructor), we can calculate it at exception throwing time, by re-parsing the source in a similar way to the existing call site rendering. This slightly decreases bytecode size and slightly decreases the amount of work the bytecode compiler needs to do. In the future, it could also allow us to give more detailed error messages, as we now have access to the entire AST and are on the slow path anyway.

Class declarations support structured heap data that is a subtype of HeapObject. Only fields of Object subtypes (both strong and weak) are currently supported (no scalar fields yet). With this CL, both the field list macro used with the C++ DEFINE_FIELD_OFFSET_CONSTANTS macro (to make field offset constants) as well as the Torque "operator '.field'" macros are generated for the classes declared in Torque. This is a first step to removing the substantial amount of duplication and boilerplate code needed to declare heap object classes. As a proof of concept, and handful of class field definitions, including those for non trivial classes like JSFunction, have been moved to Torque.

Originally, the NativeModule and the WasmModuleObject were created together, and the streaming decoder was notified after the WasmModuleObject was created. A recent CL (https://crrev.com/c/1402544), however, changed that. The NativeModule gets created before compilation starts, the WasmModuleObject, however, gets created after compilation. The streaming decoder only needs the NativeModule to register a callback before compilation. Therefore this CL we change the notification of the streaming decoder to receive only the NativeModule, not the WasmModuleObject, before starting compilation.
