 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.
