Windows is supported: https://lab.llvm.org/buildbot/#/builders/172 :)

The only thing that's different to other sub-projects is the value of `LLVM_ENABLE_PROJECTS`, i.e. use `-DLLVM_ENABLE_PROJECTS=clang;mlir;flang;llvm` when running CMake. Keep in mind that Flang is slow to build and consumes lots of memory, sadly.

If we can't test on MinGW, then we could also just add a note in the docs.
