// The current various uses for constant values (OpAccessChain, OpTypeArray, LocalSize, etc) all have spec langauge making sure they
// are scalar ints. It is also not valid for any of these use cases to have a negative value. While it is valid SPIR-V to use 64-bit
// int, found writting test there is no way to create something valid that also calls this function. So until a use-case is found,
// we can safely assume returning a uint32_t is ok.
