nit: I know this is not part of your change, but can we move down the
"locals_count" variable to where it's used, so that the code is in sync with
ia32 and x64?

+  // Generators allocate locals, if any, in context slots.
+  ASSERT(!(info->function()->is_generator() && locals_count));
 
   info->set_prologue_offset(masm_->pc_offset());
