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.

Would be more useful if we could use "const char * const *", but there's
a long standing bug where gcc warns about incompatible pointers when you
try to pass in "char **". We can at least constify the array itself as
gcc will not warn in that case.
