Subject: [PATCH] scripts/gdb: add cache for type objects

Type lookups are very slow in gdb-python which is often noticeable when
iterating over a number of objects.  Introduce the helper class CachedType
that keeps a reference to a gdb.Type object but also refreshes it after an
object file has been loaded.
