Optimize Info Table Provenance Entries (IPEs) Map creation and lookupwip/IPE_hashmap

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:

+Note [The Info Table Provenance Entry (IPE) Map]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+IPEs are stored in a hash map from info table address (pointer) to IPE. This
+ensures cheap lookup and traversal.
+
+Unfortunately, inserting into the hash map is relatively expensive. To keep
+startup times low, there's a temporary data structure that is optimized for
+collecting IPE lists on registration.
+
+It's a singly linked list of IPE list buffers. Each buffer contains space for
+126 IPE lists. This number is a bit arbitrary, but leaves a few bytes so that
+the whole structure might fit into 1024 bytes.
+
+On registering a new IPE list, there are three cases:
 
-void dumpIPEToEventLog(void)
-{
+- It's the first entry at all: Allocate a new IpeBufferListNode and make it the
+  buffer's first entry.
+- The current IpeBufferListNode has space in it's buffer: Add it to the buffer.
+- The current IpeBufferListNode's buffer is full: Allocate a new one and link it
+to the previous one, making this one the new current.
+
+Building the hash map is done lazily, i.e. on first lookup or traversal. For
+this all IPE lists of all IpeBufferListNode are traversed to insert all IPEs.
+
+After the content of a IpeBufferListNode has been inserted, it's freed.
