    [wasm simd] Fuzz test the shuffle opcode · d950fc47
    Bill Budge authored
    - Reorganizes shuffle tests into tabular form.
    - Adds a test that composes random numbers of random shuffles to
      make new shuffles.
    - Adds a test that generates functions to compute a complex expression
      consisting of shuffles, and compares interpreter results to compiled
      code results.
    - Fixes a problem with temp register exhaustion on ARM 32-bit.
    - Matches identity shuffles (returning first or second operand
      unchanged) and uses EmitIdentity() for these.
