X87: fix a check error for deoptimization.

X87: fix a check error for deoptimization.

   This CL is a fix for https://codereview.chromium.org/1411223010. (X87: fix
   the deoptimization issue.).

   ArchDeoptimize instruction may contains duplicated x87 double register as input
   parameters. So the scope check is not correct.
