#3803: addCoverageTicksTobind should not panic when file location is Nothing
---------------------------------+------------------------------------------

compiler/deSugar/Coverage.lhs:
{{{
addCoverageTicksToBinds dflags mod mod_loc tyCons binds = do
let orig_file =
case ml_hs_file mod_loc of
Just file -> file
Nothing -> panic "can not find the original file
during hpc trans"
}}}
Is there any reason for this function to panic? It is the only function
(at least in my use-case) of the GHC API that panics on ms_hs_file =
Nothing. I suggest to handle this more graceful and return emptyHpcInfo
and emptyModBreaks just as in the case of file ending in .boot
