    analyzer: add .fpath.txt dumps to -fdump-analyzer-feasibility

    (cherry picked from r13-6-gd8586b00dd00a1783862da5f0c8811a740400074)

    I found this extension to -fdump-analyzer-feasibility very helpful when
    debugging PR analyzer/105285.

    gcc/analyzer/ChangeLog:
            * diagnostic-manager.cc (epath_finder::process_worklist_item):
            Call dump_feasible_path when a path that reaches the the target
            enode is found.
            (epath_finder::dump_feasible_path): New.
            * engine.cc (feasibility_state::dump_to_pp): New.
            * exploded-graph.h (feasibility_state::dump_to_pp): New decl.
            * feasible-graph.cc (feasible_graph::dump_feasible_path): New.
            * feasible-graph.h (feasible_graph::dump_feasible_path): New
            decls.
            * program-point.cc (function_point::print): Fix missing trailing
            newlines.
            * program-point.h (program_point::print_source_line): Remove
            unimplemented decl.

    gcc/ChangeLog:
            * doc/invoke.texi (-fdump-analyzer-feasibility): Mention the
            fpath.txt output.
