RFR(S): 8214922: Add vectorization support for fmin/fmax

[Roland Westrelin]

Hi Pengfei,

> Webrev: http://cr.openjdk.java.net/~pli/rfr/8214922/webrev.00/

 600     case Op_MinF:
 601       assert(bt == T_FLOAT, "must be");
 602       if (Matcher::max_vector_size(T_FLOAT) > 2) {
 603         vopc = Op_MinReductionV;
 604       }
 605       break;

Why is the Matcher::max_vector_size(T_FLOAT) > 2 check needed?

Roland.
