  -----------
  [MergeICmps] Separate out BCECmp and use Optional (NFC)

Separate out the BCECmp part from BCECmpBlock, which just stores
the comparison atoms without the branch instruction. At the same
time switch the code to return Optional<> rather than objects in
invalid state and partially constructed objects.
