Implement compile-time optimization for min() and max().
`evaluate_intrinsic_1_of_type` was rewritten and now supports up to
three arguments. The following APIs are now optimizable:
$genType min($genType x, $genType y);
$genType min($genType x, float y);
$genHType min($genHType x, $genHType y);
$genHType min($genHType x, half y);
$genIType min($genIType x, $genIType y);
$genIType min($genIType x, int y);
$genType max($genType x, $genType y);
$genType max($genType x, float y);
$genHType max($genHType x, $genHType y);
$genHType max($genHType x, half y);
$genIType max($genIType x, $genIType y);
$genIType max($genIType x, int y);
