    Don't use unsafeGlobalDynFlags in optCoercion
    
    This plumbs DynFlags through CoreOpt so optCoercion can finally
    eliminate its usage of `unsafeGlobalDynFlags`.
    
    Note that this doesn't completely eliminate `unsafeGlobalDynFlags`
    usage from this bit of the compiler. A few uses are introduced in
    call-sites where we don't (yet) have ready access to `DynFlags`.
    
    Test Plan: Validate
