    Start using `-W` instead of `-f(no-)warn` in some places · 437ebdda
    Herbert Valerio Riedel authored
    This replaces some occurences of `-f(no-)warn` with the new `-W`-aliases
    introduced via 2206fa8c / #11218, in cases which are guaranteed
    to be invoked with recent enough GHC (i.e. the stage1+ GHC).
    
    After this commit, mostly the compiler and the testsuite remain using
    `-f(wo-)warn...` because the compiler needs to be bootstrappable with
    older GHCs, while for the testsuite it's convenient to be able to quickly
    compare the behavior to older GHCs (which may not support the new flags yet).
    
    The compiler-part can be updated to use the new flags once GHC 8.3 development
    starts.
