This change is mostly about making sure that Flang's driver recognises
LLVM IR and BC as supported as supported file formats. To this end,
`isFortran` is extended and renamed as `isSupportedByFlang` (the latter
better reflects the new functionality).

Some new tests are added to verify that the target triple is overridden
by the frontend driver's default or the value specified with `-triple`.
Strictly speaking, this is not a functionality that's added here.
However, this patch enables us to write such tests and hence I'm
including them here.
