Change InstId dumping to hex numbers that include the tag (#6175)

This change makes dumping and debugging work again with InstIds that are
now tagged with the CheckIRId. The textual representation of an InstId
is changed from `irN.instM` back to `instM` but the `M` is now a hex
value with the tag as part of it, which is the same number that is
physically in the `InstId::index` field. This prevents any cases where
we would potentially print incorrect values for large InstIds.

We teach the `dump` command in lldb to parse hex values for InstId so
that we can paste these numbers back into the debugger.
