BTW, this debug check was removed from ARM because I couldn't think of a simple
way to do it with only one scratch register---and didn't want to pass in a
scratch register just for debug code.

It's still on IA32 and x64, so maybe you can think of a good way to introduce it
here?

-    lw(t9, MemOperand(dst, Context::SlotOffset(Context::FCONTEXT_INDEX)));
-    Check(eq, "Yo dawg, I heard you liked function contexts "
-              "so I put function contexts in all your contexts",
-               dst, Operand(t9));
-  }
 }
