      [wasm] [interpreter] Box floats for certain operations · 319b7868
      Clemens Hammacher authored
      There are wasm operations which operate on floats or double, but they
      need to preserve the exact bit pattern. Thus they cannot be stored and
      passed as float or double, since that might flip the signaling NaN bit.
      This CL extends WasmValue to store floats and doubles as bit pattern,
      and adds accessors to extract them as Float32 or Float64.
      The interpreter is changed to execute certain operations (i32.abs,
      i32.neg, i64.abs, i64.neg, f32.reinterpret/i32, f64.reinterpret/i64) on
      boxed floats.
