### GPGPU Bitcasting functions

TODO
| Name | Type | Description |
| :--------------- | :----------------- | :----------------------------------------------------------------------------------------- |
| `gbitcast{I, O}` | `I -> O` | Manually constructs a bitcast operation on the input. You probably won't use this directly |
| `asU32` | `gu32 -> gu32` | Returns the original value back |
| `asU32` | `gi32 -> gu32` | Bitcasts the `gi32` to a `gu32` |
