This PR both adds in-source documentation on what to look out for when adding a new (X86) feature set and adds all that are detectable at run-time in Rust stable as of 1.27.0. This should only enable the use of the corresponding LLVM intrinsics. Actual intrinsics need to be added separately in rust-lang/stdarch. It also re-orders the run-time-detect test statements to be more consistent with the actual list of intrinsics whitelisted and removes underscores not present in the actual names (which might be mistaken as being part of the name) |

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.
