      [builtins] Make Math.ceil, Math.trunc and Math.round optimizable. · 8d20f2fe
      bmeurer authored
      Migrate Math.ceil, Math.round and Math.trunc to TurboFan code stubs,
      similar to what we did with Math.floor, and make these builtins properly
      optimizable in TurboFan via appropriate simplified operators NumberCeil,
      NumberRound and NumberTrunc, which are intended to be reusable for
      ToInteger and ToLength optimizations that will be done in a followup CL.
      
      Also allows us to kill the funky %RoundNumber runtime function, which
      was quite heavy.
      
      Improve test coverage for Math.ceil and Math.trunc a lot, especially
      making sure that we also properly trigger the TurboFan builtin reducer
      case.
