The {ToV8Vector} method returns a {i::Vector} pointing to heap-allocated memory, but that memory was never free'd. Since we already have a {ToVector} method returning a {std::vector}, this CL switches to that one instead.

In a few places we incorrectly assumed to know the instance type of the heap object. In particular, in JSCallReducer::ReduceDataViewAccess, doing map inference on the receiver and determining that all maps are JSDataView maps does not guarantee that the receiver is a JSDataView constant because we might deopt before getting to the data view operation.

Integer splats (especially for sizes < 32-bits) does not directly translate to a single instruction on ia32. We can do better for special values, like 0, which can be lowered to `eor dst dst`. We do this check in the instruction selector, and emit a special opcode kX64S128Zero. Also add a unittest to verify this optimization, and necessary raw-assembler methods for the test.

StringAdd_CheckNone is called from Turbofan with an empty context. This builtin needs context when calling the StringAdd runtime function which could potentially throw. Turbofan does bounds check before calling this builtin so it is safe to pass an empty context. To enable TNodification of this builtin this cl adds a new type that either accepts a context or an empty context (Smi::Zero) and updates the builtin to use this new type.

While writing a new test I realized that the test did not fail if running into a CHECK or UNREACHABLE *after* printing the last expected line. That is because both stderr and the exit status are ignored. This CL fixes that. This will uncover a lot of memory leaks, which I plan to address in follow-up CLs.

The inspector fuzzer is running into timeouts most of the time currently, because the test explicitly needs to quit execution. Make fuzzing more efficient by adding a watchdog thread which stop execution after 2 seconds. This will still result in valid test cases, i.e. everything that was executed within those two seconds will count as covered code. Drive-by: Slightly simplify the storage of task runners. No need to clear the vector after termination.
