    Implement TH addCorePlugin.
    
    This allows template-haskell code to add plugins to the compilation
    pipeline. Otherwise, the user would have to pass -fplugin=... to ghc.
    
    For now, plugin modules in the current package can't be used. This is
    because when TH runs, it is too late to let GHC know that the plugin
    modules needed to be compiled first.
    
    Test Plan: ./validate
