Implement f32x4.pmin, f32x4.pmax, f64x2.pmin, and f64x2.pmax.

Due to the way minps/maxps/minpd/maxpd works [0], we swap lhs and rhs.
This is similar to the way TurboFan does this [1].

[0] "If the values being compared are both 0.0s (of either sign), the
value in the second operand (source operand) is returned." but pmin/pmax
wants to return the lhs (which follows the definition of std::min<T> in
C++ STL.)
