    Merge libiberty: Initialize d_printing in all cplus_demangle_fill_* functions.
    
    While integrating the d_printing recursion guard change into gdb I
    noticed we forgot to initialize the demangle_component d_printing
    field in cplus_demangle_fill_{name,extended_operator,ctor,dtor}.
    As is done in cplus_demangle_fill_{component,builtin_type,operator}.
    It happened to work because in gcc all demangle_components were
    allocated through d_make_empty. But gdb has its own allocation
    mechanism (as might other users).
    
    libiberty/ChangeLog:
    
           * cp-demangle.c (cplus_demangle_fill_name): Initialize
           demangle_component d_printing.
           (cplus_demangle_fill_extended_operator): Likewise.
           (cplus_demangle_fill_ctor): Likewise.
           (cplus_demangle_fill_dtor): Likewise.
    
    gdb/ChangeLog:
    
           * cp-name-parser.y (make_empty): Initialize d_printing to zero.
