amdgcn: add fmin/fmax patterns

Add fmin/fmax for scalar, vector, and reductions.  The smin/smax patterns are
already using the IEEE compliant hardware instructions anyway, so we can just
expand to use those insns.

gcc/ChangeLog:

* config/gcn/gcn-valu.md (fminmaxop): New iterator.
(<fexpander><mode>3): New define_expand.
(<fexpander><mode>3<exec>): Likewise.
(reduc_<fexpander>_scal_<mode>): Likewise.
* config/gcn/gcn.md (fexpander): New attribute.
