      [turbofan] Try hard(er) to use smi representation for float64 values. · 7709e41a
      bmeurer authored
      Previously ChangeLowering would always box float64 values when going to
      tagged representation, but that introduces a lot of deoptimizer loops
      and polymorphism into TurboFan, which is unfortunate and unnecessary.
      
      This adds some logic to ChangeFloat64ToTagged to try harder to create a
      Smi when going from Float64 to Tagged, instead of always allocating a
      HeapNumber.  This might need some additional tweaking, but at least it
      makes it possible to start comparing TurboFan and Crankshaft for some
      regular JavaScript.

      In the shell sample don't print the result of executing a script, only
      evaluating expressions.
      
      Fixed issue when building samples on Windows using a shared V8
      library.  Added visibility option on Linux build which makes the
      generated library 18% smaller.
      
      Changed build system to accept multiple build modes in one build and
      generate seperate objects, libraries and executables for each mode.
      
      Removed deferred negation optimization (a * -b => -(a * b)) since this
      visibly changes operand conversion order.
      
      Improved parsing performance by introducing stack guard in preparsing.
      Without a stack guard preparsing always bails out with stack overflow.
