    [TTG: Handling Source Locations] Foundation and Pat
    Trac Issue: #15495
    This patch removes the ping-pong style from `HsPat` (only, for now), using the plan laid out at https://ghc.haskell.org/trac/ghc/wiki/ImplementingTreesThatGrow/HandlingSourceLocations (solution A).
    
    - the class `HasSrcSpan`, and its functions (e.g., `cL` and `dL`), are introduced
    - some instances of `HasSrcSpan` are introduced
    - some constructors `L` are replaced with `cL`
    - some patterns `L` are replaced with `dL` view pattern
    - some type annotation are necessarily updated updated (e.g., `Pat p` --> `Pat (GhcPass p)`)
