Add round_nimm_scalar_predicate and use xBm

Add round_nimm_scalar_predicate for scalar SSE integer to floating point
conversions since round_nimm_predicate is for vector operand.

round_constraint can't be used on vector SSE patterns since it is mapped
to "vm".  The "xBm" constraint must be used in this case.
