commit 2206fa8cdb1209320f3690690b610320b4810de6

    Add `-W(no-)xxx` aliases for `-f(no-)warn-xxx` flags
    
    This also updates the user's guide to refer to the `-W`-based warning
    flags by default.
    
    Quoting the release note entry:
    
    | Warnings can now be controlled with `-W(no-)...` flags in addition to
    | the old `-f(no-)warn...` ones. This was done as the first part of a
    | rewrite of the warning system to provide better control over warnings,
    | better warning messages, and more common syntax compared to other
    | compilers. The old `-fwarn...`-based warning flags will remain
    | functional for the forseeable future.
    
    This is part of
    https://ghc.haskell.org/wiki/Design/Warnings
    and addresses #11218
