 Allow TcDerivInfer to compile with GHC 8.0.1

 As of ed7a830de6a2ea74dd6bb81f8ec55b9fe0b52f28 this module uses
 MultiWayIf, the parsing behavior of which changed in 8.0.2 due
 to #10807. Reformat the code so that it compiles under both 8.0.1 and
 8.0.2/8.2.1.

 Test Plan: Validate bootstrapping with 8.0.1
