X87: [crankshaft] Support ES6 tail call elimination.

  port 22938040fdb9a061babe96f004355fd79b2958a0 (r34542)

  original commit message:
  HInvokeFunction and HApplyArguments instructions now support tail calling.

  Inlining of calls at tail position is not supported yet and therefore still disabled.

  The tail-call-megatest was modified so that the usages of "arguments" object do not disable Crankshaft.
