Returns a vector of all BB address maps in the object file.

When TextSectionIndex is specified, only returns the BB address maps corresponding to the section with that index. When PGOAnalysesis specified (PGOAnalyses is not nullptr), the vector is cleared then filled with extra PGO data. PGOAnalyses will always be the same length as the return value when it is requested assuming no error occurs. Upon failure, PGOAnalyses will be emptied.
