* Synced with GENie upstream revision e78d6c1
* Add Visual Studio 2019 support
* Fix hardcoded -m64
* Switch appveyor to Visual Studio 2019
* Fix genie being built as 32-bit
* MSVC build is known to be broken currently. Let it fail until all the known issues are fixed.
* Update the packages before building
* Build with 3 threads
Appveyor VMs have only 2 cores and 8 GB RAM.
* Enable caching of pacman cache
* Add gcc build to appveyor
As tea-ci has been broken for quite a while now there has been no MINGW CI available. MINGW builds can be done in appveyor too. Tools build had to be disabled as it takes longer than the allowed 60 minutes. Wa,-mbig-obj was added to avoid "file too big" errors.
* Align appveyor gcc build configuration with travis
This will hopefully make the build fast enough not to miss the 60 minute maximum build time
* Turns out non-debug build needs -mbig-obj too
