  Log Message:
  -----------
  Restore "[MemProf] Memprof profile matching and annotation"

This reverts commit 794b7ea960ccc3222f2af582efadbc5e5c464292, and
thus restores commit a212d8da94d08e229aa8d65283e4b116310bba10, and
follow on fixes 0cd6763fa93159b84d70a5bb602c24996acaafaa,
e9ff53d42feac7fc157718523275619a8106f2f3, and
37c6a25e9ab230e5e21fa34e246d9fec55275df0.

Use a hash function (BLAKE3) instead of hash_combine/hash_code which are
not guaranteed to be stable across executions.

Additionally, it adds a "REQUIRES: x86_64-linux" to the tests that have
raw profile inputs to avoid failures on big endian bots.
