`VMAX`

(Vector Maximum) compares corresponding
elements in two vectors, and copies the larger of each pair into
the corresponding element in the destination vector.

`VMIN`

(Vector Minimum) compares corresponding
elements in two vectors, and copies the smaller of each pair into
the corresponding element in the destination vector.

`VPMAX`

(Vector Pairwise Maximum) compares adjacent
pairs of elements in two vectors, and copies the larger of each
pair into the corresponding element in the destination vector. Operands and
results must be doubleword vectors.

`VPMIN`

(Vector Pairwise Minimum) compares adjacent
pairs of elements in two vectors, and copies the smaller of each
pair into the corresponding element in the destination vector. Operands
and results must be doubleword vectors.

max(+0.0, -0.0) = +0.0.

min(+0.0, -0.0) = -0.0

If any input is a NaN, the corresponding result element is the default NaN.
