Before the existence of "= delete", we were enforcing that the DISALLOW_* macros were used in the private: section of classes only. This is not needed any more, hence remove the comment on the macros. Also, introduce macros for making types move-only, and use them instead of our special macro in wasm.

Inlining heuristics in Turbofan used ast node count. Bytecode size is a better approximation of the size of the graph than the ast node count. This cl changes the heuristics to use the bytecode size instead. Also removing the ast_node_count filed in the shared function info. It was used only for the inlining heuristics. Also removed the max_inlined_source_size flag which is no longer used.

Async functions and generator declarations are only permitted as StatementListItems, not as ExpressionStatements, and therefore not as the entire body of an if statement, etc. Previously, they were incorrectly permitted. However, ChakraCore and SpiderMonkey seem to ban them in this context, and the feature was introduced relatively recently, so it is likely to be web-compatible to ship the prohibition. This patch also unifies the error message wording of async functions and generators to ordinary functions, explaining more clearly what the issue is.

Ulan Degenbaev authored
This patch adds a new intrinsic: %DebugTrackRetainingPath(object). Calling the intrinsic in JS code saves a weak reference to the given object in GC internal table of tracked objects. Each subsequent full GC prints to stdout the retaining path for each tracked object (if it is still alive). The retaining path is the real path that the marker took from the root set to the tracked object. This is useful for investigating of memory leaks: 1) Add %DebugTrackRetainingPath(leaking_object) in JS code. For example: function foo() { let x = { bar: "bar"}; %DebugTrackRetainingPath(x); return () => { return x; } } let closure = foo(); gc(); 2) Run d8 with --allow-natives-syntax --track-retaining-path --expose-gc. 3) Check the retaining path in stdout. For more detailed inspection, run d8 in gdb and set breakpoint in v8: :internal::Heap::PrintRetainingPath.

Temporary check ensuring no regression while we get the wasm code off the GC heap, and and until we de-contextualize wasm code. We expect the only embedded objects to be: CEntryStub, undefined, and the various builtins for throwing exceptions like OOB. These are all immovable because they are snapshotted. Additionally, we embed references to the FixedArray that backs WebAssembly.Table. That will be replaced separately with a native data structure. Once the Table is native, we can generate Wasm code off the GC heap, as long as the embedded objects are immutable, which is the property we check for here. That greatly simplifies a subsequent step, which is to replace those dependencies with a isolate-independent solution. The source of simplification is that we don't have to worry about moving pointers.
