perf auxtrace: Add a hashtable for caching
Decoding AUX area data may involve walking object code. Rather than
repetitively decoding the same instructions, a cache can be used to
cache the results.
This patch implements a fairly generic hashtable with a 32-bit key that
could be used for other purposes as well.
