On Liftoff bailout, instead of binding all unbound labels (to avoid triggering DCHECKS in their destructor), just Unuse them.

In some test-run-wasm-js cctests we want to call wasm code through the js-to-wasm wrapper. This did not work if we wanted to run the wasm code in the interpreter, because we never compiled a WasmInterpreterEntry, and we did not patch the jump table. With this CL we do both now.

jumbo.gni will check whether use_jumbo_build is set or not and if it's not set it will just check that |jumbo_excluded_sources| lists do not include non-existing files. That means that there is little/nothing to lose by always routing v8_source_set that way, and it adds a bit in build file simplicity and local checking of |jumbo_excluded_sources|.

During execution, the tier can be switch from Liftoff to TurboFan. We already handle this in some locations by getting the tier before execution, so that we later know which was the requested tier for that unit. In the case of the --wasm-tier-mask-for-testing flag, this accounting was not right because the tier was already switched in the constructor. This CL changes the compilation units to store both the requested and the executed tier explicitly, so we know which counter to decrement when the unit finishes.

Currently, errors somewhere deep in a promise chain are not reported as test failures. We would print the error, but still return with exit status 0. This CL fixes this to treat any uncaught exception as failure, as we already do in {Shell::ExecuteString}.

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.

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.
