My understanding is that it is being actively developed. Currently for
numerical code, the LLVM backend performs better than the native codegen.
I also think that the LLVM backend is the only option for ARM.

As someone else stated, use `-keep-llvm-files` but be aware that
GHC uses a custom calling convention so calling into GHC generated
LLVM code is non-trivial.
