We need members of the global namespace to point to the global translation unit decl.
Thus we will append DECL_CONTEXT of global namespace to cache in preload.

This doesn't fix any tests, but helps towards making the tree nodes identicals in pph-mode.

Tested with bootstrap build and pph regression testing.

	* pph-streamer.c (pph_preload_common_nodes):
	Append DECL_CONTEXT of global_namespace to cache.
