    Use Info Table Provenances to decode cloned stack (#18163) · 29717ecb

    Emit an Info Table Provenance Entry (IPE) for every stack represeted info table
    if -finfo-table-map is turned on.
    
    To decode a cloned stack, lookupIPE() is used. It provides a mapping between
    info tables and their source location.
