Log:
[NFC] Make some ObjectFormatType switches covering

Summary:
This patch removes the `default` case from some switches on
`llvm::Triple::ObjectFormatType`, and cases for the missing enumerators
are then added.

For `UnknownObjectFormat`, the action (`llvm_unreachable`) for the
`default` case is kept.

For the other unhandled cases, `report_fatal_error` is used instead.
