x86: fix CVT{,T}PD2PI insns
With just an "m" constraint misaligned memory operands won't be forced
into a register, and hence cause #GP. So far this was guaranteed only
in the case that CVT{,T}PD2DQ were chosen (which looks to be the case on
x86-64 only).
Switch the second alternative to Bm and also replace
nonimmediate_operand by vector_operand.
