The fix for PR demangler/70909 and 67264 (endless demangler recursion)
catches when a demangle_component is printed in a cycle. But that doesn't
protect the call stack blowing up from non-cyclic nested types printed
recursively through d_print_comp. This can happen by a (very) long mangled
string that simply creates a very deep pointer or qualifier chain. Limit
the recursive d_print_comp call depth for a d_print_info to 1K nested
types.
libiberty/ChangeLog:
* cp-demangle.c (MAX_RECURSION_COUNT): New constant.
(struct d_print_info): Add recursion field.
(d_print_init): Initialize recursion.
(d_print_comp): Check and update d_print_info recursion depth.

d_add_substitution can fail for various reasons, like when the subs array
is full. If d_add_substitution fails d_substitution should return NULL
early and not try to continue. Every other call of d_add_substitution
is handled in the same way.
libiberty/ChangeLog:
* cp-demangle.c (d_substitution): Return NULL if d_add_substitution
fails.

The d_info field did_subs was used for estimating the string output
size. It was no longer used when the malloc-less callback interface
was introduced in 2007 (svn r121305). But the field was still updated.
When backtracking was introduced in 2013 (svn r205292) did_subs was
also added to the d_info_checkpoint struct. But except for updating
the field it was still not used.
Since it is never used just stop updating the field and remove it
from the two structs.

* cp-demangle.h (struct d_info): Remove did_subs field.
* cp-demangle.c (struct d_info_checkpoint): Likewise.
