The literal index is being pushed onto the stack while evaluating
the non-constant subexpressions, but never used in fullcodegen (and
hence not used in the optimizing compilers).

  original commit message:
  There's no point in collecting feedback for super constructor calls,
  because in all (interesting) cases we can gather (better) feedback from
  other sources (i.e. via inlining or via using a LOAD_IC to get to the
  [[Prototype]] of the target).  So CallConstructStub is now only used
  for new Foo(...args) sites where we want to collect feedback in the
  baseline compiler.  The optimizing compilers, Reflect.construct and
  super constructor calls use the Construct builtin directly, which allows
  us to remove some weird code from the CallConstructStub (and opens the
  possibility for more code sharing with the CallICStub, maybe even going
  for a ConstructICStub).

  Also remove the 100% redundant HCallNew instruction, which is just a
  wrapper for the Construct builtin anyway (indirectly via the
  CallConstructStub).

  Drive-by-fix: Drop unused has_function_cache bit on Code objects.

concerend with the straight-forward Array() and Array(length) cases,
