Commit 5f12f4ff9078455cad9d4806da01f570553a5bf9 made suppressing inline namespaces
when printing typenames default to true. As we're using the inline namespaces
in LLDB to construct internal type names (which need internal namespaces in them
to, for example, differentiate libc++'s std::__1::string from the std::string
from libstdc++), this broke most of the type formatting logic.
