  -----------
  [MachineSink] Check predecessor/successor relationship between two basic blocks involved in critical edge splitting (#98540)

Fix an issue in #97618 - if the two basic blocks involved are not
predecessor / successor to each other, treat the candidate as illegal
for critical edge splitting.

Closes #98477 (checked in test copied from its comment).
