Some GDB versions require all prettyprinter classes to define to_string.
This commit adds these definitions.

This isn't perfect, since it doesn't use lazy_string - so if the
std::string does contain unprintable characters it might fail, but seems
better than nothing & LLVM doesn't generally store binary data in
std::strings.
Instead of using the type llvm::StringMapEntry<{stringified_value_type}>
use only the base class llvm::StringMapEntryBase and calculate the
offsets of the member variables manually. The approach with stringifying
the name of the value type is pretty fragile as it can easily break with
local and dependent types.

Make sure all print statements are compatible with Python 2 and Python3 using
the `from __future__ import print_function` statement.

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)
