        PR debug/27574
        * cgraph.h: New abstract_and_needed member to struct cgraph_node.
        * cgraphunit.c (cgraph_analyze_functions): Flag abstract functions
        - which clones are reachable - as "abstract and needed".
        * cgraph.c (cgraph_release_function_body):  If a node is "abstract and
needed",
        do not release its DECL_INITIAL() content because that will be needed
to emit
        debug info.
