John Stiles 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)
