commit 22dba98f2b22141d8238d7e7a42141495945f1cf

    Fix recompilation tracking on signatures.
    
    Summary:
    Previously we weren't tracking these dependencies at all,
    because we couldn't "find" the interface for {A.H}.  Now
    we've associated hole names to the correct module identity
    so we will pick them up.
