[pph] Add cp_global_trees to cache in preload (issue4635077)

Add the cp_global_trees to the cache during the preload.

Those are preconstructed trees which we only need the pointers to (i.e. they should be identical in both the .cc and .h)

One exception to this is the keyed_classes tree which is generated during parsing.

We will need to merge the keyed_classes tree eventually when working with multiple pph's.

	* pph-streamer.c (pph_preload_common_nodes):
	Add cp_global_trees[] to cache.

	* g++.dg/pph/x1typerefs.cc: Remove xfail.
