This CL attempts to fix a chrome crash seen in the wild. Without a reproducer, the current working theory is that we hit a 'null' context in some edge case, causing us to access an empty handle. This CL prevents the empty context handle to be dereferenced.

Add kWasmS128 to the list of supported types, and implement Fill for all the architectures so that LocalGet works. Add a new test file to contain tests that run only on Liftoff, and assert that the code is indeed compiled by Liftoff. We cannot rely on the nooptimization variant for testing because by default, if Liftoff compilation fails, it will fall back to Turbofan, and we accidentally get a test passing. We skip these tests on mips architecture that don't support SIMD, since there is no way to implement these, and we don't have a "lowering" phase for Liftoff. As we implement more of SIMD in Liftoff, we can add more tests to this file and ensure correctness. Future patches will introduce support for globals and params.

Tests which set the --perf-prof flag leave behind a file in the current working directory every time they execute. In order to avoid this, this CL introduces a --perf-prof-delete-file flag, which removes this file right after creating it. This still allows the process to write to it via the open handle, but the file will be gone afterwards, even if the process crashes or gets killed while executing.

This fixes local names that are the string representation of a valid element index. Even though both the Liftoff and the interpreter-based test are changed, only the latter needs to be fixed right now since Liftoff does not use the names currently. Modifying the test just ensures that we implement this correctly once we use the name.
