x86/32on64: misc adjustments to call gate emulation

- There's no 32-bit displacement in 16-bit addressing mode.
- It is wrong to ASSERT() anything on parts of an instruction fetched
  from guest memory.
- The two scaling bits of a SIB byte don't affect whether there is a
  scaled index register or not.
