Relaxed f32x4 and f64x2 min and max.

These instructions only guarantee results when the inputs are non nans,
and when the inputs are not 0s of opposite signs.

Drive-by rename of instruction codes to be Minps/Maxps/Minpd/Maxpd
since they map down exactly to a single instruction.

ia32 port of c3f346b7.
