B.4.247. `POR': MMX Bitwise OR
------------------------------

     POR mm1,mm2/m64               ; 0F EB /r             [PENT,MMX]
     POR xmm1,xmm2/m128            ; 66 0F EB /r     [WILLAMETTE,SSE2]

   `POR' performs a bitwise OR operation between its two operands (i.e.
each bit of the result is 1 if and only if at least one of the
corresponding bits of the two inputs was 1), and stores the result in
the destination (first) operand.
