It is not pretty! But LLVM has no way to query this information with their C API.

It generates these globals (intended for `src/build_settings_microarch.cpp`:

## Usage
1. Make sure the table of architectures at the top of the python script is up-to-date (the triple can be any valid triple for the architecture)
1. `./build.sh`
1. `./build_featuregen.sh`
1. `python3 featuregen.py`
1. Copy the output into `src/build_settings.cpp`
