Same as for the x64 version, I don't see why the details of the stack layout are
relevant for this method.

   // [esp + (2 * kPointerSize)]: literal index.
   // [esp + (3 * kPointerSize)]: literals array.
-  // eax: literal index.
-  // ecx: literals array.
+  // ecx: boilerplate array.
   ASSERT(mode != FastCloneShallowArrayStub::CLONE_ANY_ELEMENTS);
 
   // All sizes here are multiples of kPointerSize.
