Also, `-Xarch` has grown non-obvious usage nuances that should probably be
mentioned in clang docs. We do mention them in openmp docs at the moment, but
this is something that should be exposed somewhat more prominently, as this is
pretty much the only mechanism we have for granular control of the offload
build parameters.
It's not uncommon to need different optimization options for different GPU
variants. E.g. we want to compile with host-side debug info only, or specify
different inlining/unrolling thresholds for different GPUs. All of those are
effectively end-user facing options and should be documented.
