John Stiles 7f17d36c2c 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);
