Offload device LLVM's offload functionality usually expects an extra dyn_ptr argument. We could avoid it,b ut likely gonna need it very soon in one of the follow-up PRs (e.g. to request shared memory). So we might as well already add it. This PR adds a %dyn_ptr ptr to GPUKernel ABI functions, if the offload feature is enabled. WIP r? ```@ghost```
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
