  Log Message:
  -----------
  [Metadata] Preserve MD_prof when merging instructions when one is missing.

Preserve branch weight metadata when merging instructions if one of the
instructions is missing metadata. This is similar in behaviour to what
we do today for other types of metadata such as mmra, memprof and
callsite metadata.
