Detailed Description

An abstract event subclass describing the creation of a region that
is significant for a diagnostic.

There are too many combinations to express region creation in one message,
so we emit multiple region_creation_event instances when each pertinent
region is created.

The events are created by pending_diagnostic's add_region_creation_events
vfunc, which by default creates a region_creation_event_memory_space, and
if a capacity is known, a region_creation_event_capacity, giving e.g.:
  (1) region created on stack here
  (2) capacity: 100 bytes
but this vfunc can be overridden to create other events if other wordings
are more appropriate foa a given pending_diagnostic.
