      [csa] Canonicalize empty elements in AllocateJSArray · 2859dba7
      Jakob Gruber authored
      Prior to this, AllocateJSArray would go ahead and allocate an empty
      FixedArray as elements if passed any capacity that is not a compile-time
      constant 0.
      
      Things break later on since we rely on the fact that empty fixed arrays
      are always canonicalize, and we use
      
        obj.elements == empty_fixed_array_constant
      
      interchangeably with
      
        obj.elements.length == 0.
      
      This CL introduces two new branches in AllocateJSArray: one if the
      capacity is known to be non-zero; and another that explicitly
      distinguishes between 0 and non-zero capacities.
