In CUDA/HIP a function may become implicit host device function by
pragma or constexpr. A host device function is checked in both
host and device compilation. However it may be emitted only
on host or device side, therefore the diagnostics should be
deferred until it is known to be emitted.

Currently clang is only able to defer certain diagnostics. This causes
false alarms and limits the usefulness of host device functions.

This patch lets clang defer all diagnostics for host device functions.

It is NFC for other languages.
