Optimize Info Table Provenance Entries (IPEs) Map creation and lookup
Using a hash map reduces the complexity of lookupIPE(), making it non linear.
On registration each IPE list is added to a temporary IPE lists buffer, reducing
registration time. The hash map is built lazily on first lookup.
IPE event output to stderr is added with tests.
For details, please see
Note [The Info Table Provenance Entry (IPE) Map].
A performance test for IPE registration and lookup can be found here:
