tree streamer_alloc_tree	(	struct lto_input_block *	ib,
		struct data_in *	data_in,
		enum LTO_tags	tag
	)

Materialize a new tree from input block IB using descriptors in
   DATA_IN.  The code for the new tree should match TAG.  Store in
   *IX_P the index into the reader cache where the new tree is stored.

Read all the language-independent bitfield values for EXPR from IB.
   Return the partially unpacked bitpack so the caller can unpack any other
   bitfield values that the writer may have written.

   contains tables and descriptors for the file being read.
