Completes libc's cxxabiv1 data surface relative to the aerolib export list: the five missing category vtables (__shim, __enum, __array, __pbase, __pointer_to_member), _ZTISt9type_info plus the eleven _ZTIN10__cxxabiv1* records forming the real single-inheritance chain down to std::type_info, and the fifty _ZTIP/_ZTIPK builtin pointer records whose pointees are the fundamental records. Every category vtable's typeinfo slot now addresses its exported _ZTIN record instead of a host type_info, so typeid of a guest typeinfo object resolves to the canonical symbol.
