Log:
This patch adds more trees to the preloaded tree cache.  This avoids
common trees, built at compiler initialization time, to be streamed
out to PPH images.

These trees are in:

	- type_hash_table: The private hash table used in tree.c to
	  record canonical types.  To avoid exposing this table out of
	  tree.c, I added a traversal routine with a callback argument
	  (type_hash_table_traverse).

	- Builtin types registered with record_builtin_type.  I added
	  a routine pph_register_builtin_type that is called for every
	  builtin type.  We later record those types in
	  pph_cache_preload.

Another piece of private state that needs to be written out is
canonical_template_parms and nonstandard_integer_type_cache.  I added
writer and reader routines to pt.c to do deal with
canonical_template_parms and traversal+callback iterators in tree.c to
deal with nonstandard_integer_type_cache (to avoid middle-end routines
to have to know about PPH).
