Emit synthetic functions before function constants. Support use of spvQuantizeToF16() in function constants for numerical behavior consistency with the op code. Ensure subnormal results from OpQuantizeToF16 are flushed to zero per SPIR-V spec. Adjust SPIRV-Cross unit test reference shaders to accommodate these changes. Any MSL reference shader that inclues a synthetic function is affected, since the location it is emitted has changed.
