Made more safe (but less effective) by using a linked list.

Based on:
	Re: [RFA] Delayed physname computation
	http://sourceware.org/ml/gdb-patches/2010-05/msg00248.html

Neither its obstack-leak.patch nor
	[patch] Fix duplicate types for single DIE
	http://sourceware.org/ml/gdb-patches/2010-05/msg00271.html
is needed as the linked list is used instead.
