InstrProf: When reading, copy the data instead of taking a reference. NFC

Browse Source 
This consolidates the logic to read instrprof records into the on disk
hash table's lookup trait and makes us copy the counter data instead
of taking references to it as we read. This will simplify further
changes to the format.

Patch by Betul Buyukkurt.
