    Hadrian: Add ./hadrian/ghci.sh script for fast development feedback
    
    Running the `./hadrian/ghci` target will load the main compiler into
    a ghci session. This is intended for fast development feedback, modules are only
    typechecked so it isn't possible to run any functions in the repl.
    
    You can also use this target with `ghcid`.
    
    The first time this command is run hadrian will need to compile a few dependencies
    which will take 1-2 minutes. Loading GHC into GHCi itself takes about 30 seconds.
    
    Internally this works by calling a new hadrian target called `tool-args`.
    This target prints out the package and include flags which are necessary
    to load files into ghci. The same target is intended to be used by other
    tooling which uses the GHC API in order to set up the correct GHC API
    session. For example, using this target it is also possible to use HIE
    when developing on GHC.
