Doing that speeds up the built clang by around 25% (which is rather significant) and reduces the size of the clang executable by almost 30%. But since the mingw target in clang/llvm is less mature and less widely tested than other llvm targets, running with assertions allows catching quite a few issues during build instead of ending up with potentially broken code.
