This includes the use of __complex and __builtin_ functions where
unprefixed entities would suffice, and the use of a union for
bit-casting between types.

Running the demangler's testsuite with CP_DEMANGLE_DEBUG defined
crashes, with:
Program received signal SIGSEGV, Segmentation fault.

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.
