Improve memory usage by reducing the lifetime of CTF types. Once a CTF type has been converted to a (complete) LLDB type, there's no need to keep it in memory anymore. For most types, we can free them right after creating the corresponding LLDB types. The only exception is record types, which are only completed lazily.

This patch also adds LLVM RTTI support to CTF type. This was suggested in D156498 <https://reviews.llvm.org/D156498> but with just one caller that didn't seem worth it yet. This patch introduced a second call site which tipped the scales.
