        * staptree.h (probe::collect_derivation_chain): Now takes vector<probe*>.
        (probe::get_alias): New virtual method.
        * elaborate.h (derived_probe::collect_derivation_chain): Now takes vector<probe*>.
        * staptree.cxx (probe::collect_derivation_chain): Now takes vector<probe*>. Don't
        cast 'this' to (derived_probe*).
        * elaborate.cxx (derived_probe::collect_derivation_chain): Now takes vector<probe*>.
        (alias_derived_probe::get_alias): New virtual method.
        (alias_derived_probe::alias): New member.
        (alias_expansion_builder::build): Call checkForRecursiveExpansion and emit a
        diagnostic if recursion is detected. Pass alias to constructor of
        alias_derived_probe.
        (alias_expansion_builder::checkForRecursiveExpansion): New method.
        * coveragedb.cxx: Pass vector<probe*> on all calls to collect_derivation_chain.
