// A GenericType is an abstract type that defines a set of types as a
// combination of Types and vector sizes.
//
// For example, if TypeList = <int, float> and VectorList = <1, 2, 4>, then it
// represents <int, int2, int4, float, float2, float4>.
//
// Some rules apply when using multiple GenericType arguments in a declaration:
//   1. The number of vector sizes must be equal or 1 for all gentypes in a
//      declaration.
//   2. The number of Types must be equal or 1 for all gentypes in a
//      declaration.
//   3. Generic types are combined by iterating over all generic types at once.
//      For example, for the following GenericTypes
//        GenT1 = GenericType<half, [1, 2]> and
//        GenT2 = GenericType<float, int, [1, 2]>
//      A declaration f(GenT1, GenT2) results in the combinations
//        f(half, float), f(half2, float2), f(half, int), f(half2, int2) .
//   4. "sgentype" from the OpenCL specification is supported by specifying
//      a single vector size.
//      For example, for the following GenericTypes
//        GenT = GenericType<half, int, [1, 2]> and
//        SGenT = GenericType<half, int, [1]>
//      A declaration f(GenT, SGenT) results in the combinations
