Teresa Johnson 8c1bd67dee [MemProf] Optionally print or record the profiled sizes of allocations (#98248) ...

This is the first step in being able to track the total profiled sizes
of allocations successfully marked as cold.

Under a new option -memprof-report-hinted-sizes:
- For unambiguous (non-context-sensitive) allocations, print the
  profiled size and the allocation coldness, along with a hash of the
  allocation's location (to allow for deduplication across modules or
  inline instances).
- For context sensitive allocations, add the size as a 3rd operand on
  the MIB metadata. A follow on patch will propagate this through to the
  thin link where the sizes will be reported for each context after
  cloning.
