Because some AES key scheduling instructions require *either* Zkne or Zknd extension, we must have a target feature to represent `(Zkne || Zknd)`. This commit adds (perma-unstable) target feature to the RISC-V architecture: `zkne_or_zknd` for this purpose. Helped-by: sayantn <sayantn05@gmail.com>
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.
