Add round_nimm_scalar_predicate and use xBmhjl/pr69171/master
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.
