      [wasm-simd][liftoff] Support SIMD locals · ba14c2f3
      Ng Zhi An authored
      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.

      [wasm] Distinguish Liftoff code from Turbofan code · 41f231a2
      Clemens Hammacher authored
      For memory tracing, output a 'T' for Turbofan code and an 'L' for
      Liftoff code. To do this, the WasmCodeWrapper now has some dispatch
      functions which work for both on-the-heap and off-the-heap code.
      We can probably refactor more code by having this mechanism.
      
      Since the output of --wasm-trace-memory differs now between Turbofan
      and Liftoff, the message test is split in two.
