X87: [stubs] Convert GrowElementsStub to TurboFan.

  original commit message:
  One caveat: the Crankshaft stub used to preserve callee-clobbered double
  registers, which is contrary to any real platform ABI that we support. Since the
  only current use of this stub is in Crankshaft, the instruction there now must
  be marked as double-clobbering. This might result in a small performance
  regression. However, when this stub is eventually used in TF-generated code, it
  will be called from deferred code that can save doubles only on the rarely-taken
  path... something that Crankshaft can't do.
