Simonas Kazlauskas dfcfaa4ec1 Do not pass through features without +/- prefix 
LLVM really dislikes this and will assert, saying something along the
lines of:

```
rustc: llvm/lib/MC/MCSubtargetInfo.cpp:60: void ApplyFeatureFlag(
  llvm::FeatureBitset&, llvm::StringRef, llvm::ArrayRef<llvm::SubtargetFeatureKV>
): Assertion
  `SubtargetFeatures::hasFlag(Feature) && "Feature flags should start with '+' or '-'"`
failed.

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.
