    Add -fcross-module-specialise flag
    
    Summary:
    As of 7.10.1 we specialize INLINEABLE identifiers defined in other
    modules. This can expose issues (compiler bugs or otherwise) in some cases
    (e.g. Trac #10491) and therefore we now provide a way for the user to disable
    this optimization.
    
    Test Plan: Successfully compile Splice.hs from Trac #10491.
