It was XFAILed because there was a bug in glibc, but that bug was fixed
nine years ago. Nowadays everyone uses a version of glibc with the bug
fixed, so we should no longer XFAIL the test.

This was a workaround for a cygwin bug which was fixed 4 years ago,
and cygwin hasn't supported affected versions for a long time.

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.
