Our tailored LLVM now uses AppVeyor and CircleCI to build Win32/Win64/Linux-x86_64 release packages and upload them to a GitHub CI release: https://github.com/ldc-developers/llvm/releases/tag/CI

It could be extended to deploy builds with enabled assertions too (for the LDC CI tests) and further tweaked to upload tagged builds to the corresponding GitHub release etc.
I already requested macOS support from CircleCI.

As next steps, we can generalize the deployment of LDC CI builds (currently Windows only) to Linux/OSX/Windows and finally automate the creation of (the most popular) release packages on tagged builds.
