For HIP, `--offload-arch=` is used by the driver to determine the GPU arch and
`-Xarch_gfx906` is allowed to pass GPU arch specific options. The option
sequences like `-Xarch_gfx906 --offload-arch=gfx1100` are not meaningful
combinations, therefore `Flags<[NoXarchOption]` is used here to diagnose such
invalid combinations. Removing this flag will lose diagnositcs for such invalid
usage.
Can we diagnose such invalid usage manually?
