gcc: Fix CVE-2016-6131 in libiberty
[NVD] -- https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-6131
The demangler in GNU Libiberty allows remote attackers to cause a denial
of service (infinite loop, stack overflow, and crash) via a cycle in the
references of remembered mangled types.
[BZ #71696] -- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71696

PR c++/71696
* cplus-dem.c: Prevent infinite recursion when there is a cycle
in the referencing of remembered mangled types.
(work_stuff): New stack to keep track of the remembered mangled
types that are currently being processed.
(push_processed_type): New method to push currently processed
remembered type onto the stack.
(pop_processed_type): New method to pop currently processed
remembered type from the stack.
(work_stuff_copy_to_from): Copy values of new variables.
(delete_non_B_K_work_stuff): Free stack memory.
(demangle_args): Push/Pop currently processed remembered type.
(do_type): Do not demangle a cyclic reference and push/pop
referenced remembered type.
