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);

7a3f5506b6 Performance experiment: disable control-flow analysis. 
This CL will be used to test for potential performance regressions (or
improvements) that we might cause by disabling this optimization pass.

It will be reverted in ~1 day.

9c9f60cdb4 Implement additional Runtime Effect intrinsic tests. 
Tested in dm:
- max(halfN, halfN)
- max(halfN, half)
- min(halfN, halfN)
- min(halfN, half)
- clamp(halfN, halfN, halfN)
- clamp(halfN, half, half)
- mix(halfN, halfN, halfN)
- mix(halfN, halfN, half)

Compiled outputs only (not in ES2):
- max(intN, intN)
- max(intN, int)
- min(intN, intN)
- min(intN, int)
- clamp(intN, intN, intN)
- clamp(intN, int, int)
- mix(halfN, halfN, boolN)  - broken in Metal/SPIR-V (skia:11222)
- mix(intN, intN, boolN)    - broken in Metal/SPIR-V (skia:11222)
