Apparently ::NodeKind is sometimes part of the name in GDB.
Without this patch I get the following error message from GDB:
`Unhandled NodeKind llvm::Twine::NodeKind::EmptyKind`.

Still prints the empty/tombstone keys (which some people would prefer,
but I find pretty noisy) because I haven't yet found a reliable way to
skip them (it requires calling into the running process to do so, which
isn't ideal for a pretty printer (doesn't work on a core file, for
example) - and gdb's ability to do so (or my ability to figure out how
to get gdb to do so) is limited) left some breadcrumbs for the next
person who might try to address that.

(some other implementations of an optional pretty printer print the full
name of the optional type (including template parameter) - but seems if
the template parameter isn't printed for std::vector, not sure why it
would be printed for optional, so erring on the side of consistency in
that direction here - compact, etc, as well)
