Fix demangler testsuite crashes with CP_DEMANGLE_DEBUG defined
Running the demangler's testsuite with CP_DEMANGLE_DEBUG defined
crashes, with:
Program received signal SIGSEGV, Segmentation fault.
0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567
567 switch (dc->type)
(gdb) bt 3
#0 0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567
#1 0x000000000040ae47 in d_dump (dc=0x7fffffffd098, indent=10) at ../../src/libiberty/cp-demangle.c:787
#2 0x000000000040ae47 in d_dump (dc=0x7fffffffd0c8, indent=8) at ../../src/libiberty/cp-demangle.c:787
Note dc=0x1, which is obviously a bogus pointer. This is the end of
d_dump recursing for a component type that that doesn't actually have
subtrees:
787 d_dump (d_left (dc), indent + 2);
788 d_dump (d_right (dc), indent + 2);
This fixes the two cases the testsuite currently trips on.

and DEMANGLE_COMPONENT_NUMBER.
