gdb: add intern methods to objfile_per_bfd_storage

Browse source 
This allows keeping the objfile_per_bfd_storage implementation details
into objfile_per_bfd_storage, instead of into objfile.  And this makes
the intern methods usable for code that only has an
objfile_per_bfd_storage to work with.

gdb/ChangeLog:

	* objfiles.h (struct objfile_per_bfd_storage) <intern>: New
	methods.
	(struct objfile) <intern>: Use
	objfile::objfile_per_bfd_storage::intern.
