  We want to check that we have a DIE describing the typedef t like this:

	.uleb128 0xc	# (DIE (0xb8) DW_TAG_typedef)
	.ascii "t\0"	# DW_AT_name
	.byte	0x1	# DW_AT_decl_file (../../prtests/test.cc)
	.byte	0xb	# DW_AT_decl_line
	.long	0x78	# DW_AT_type

  e.g, it should not haven any child DIE -- the bug here was that this
  DIE had children DIEs. So we check that the last line is immediately
  followed by a line containing the pattern "(DIE (", instead of a
  line containing a DW_AT_sibling attribute.
