[Bug python/10676] New: Would like an equality compare method for gdb.Type

[alexl at redhat dot com]

I'm doing quite a lot of type comparison in e.g. pretty printers. It would be
nice if i could compare types with ==, rather than having to manually stringify
the types and compare that. This may even be both more efficient and possibly
allow a more "correct" implementation of type comparison if multiple different
types with the same name are in use in the inferior.

Ideally we'd memoize Type objects instead of creating new ones
all the time.  That probably requires the type GC patch.
