commit 8f37f3732e5d538449cbca748d6672f517b3c5a7

    Refactor ./hadrian/ghci.sh for better error messages
    
    By separating these two lines, if the first command fails then `ghci` is
    not loaded. Before it would still load ghci but display lots of errors
    about not being able to find modules.
