This patch refactors pph_write_tree and pph_read_tree so that we can
reduce the amount of special casing we were doing. It first tries to
handle nodes based on their tree code class. The only class that
cannot be handled this way is tcc_exceptional, so we only deal with
those nodes individually.
This fixes no testcases but it simplifies the logic of the AST
streamer. I think we can now get rid of flag_pph_untree now since we
are unconditionally ICEing if a node is not handled.
Tested on x86_64. Applied to branch.
* pph-streamer-in.c (pph_in_tcc_declaration): Factor out
of pph_read_tree_body. Handle all decls.
(pph_in_tcc_type): Factor out of pph_read_tree_body. Handle
all types.
(pph_read_tree_body): Issue a fatal error if a node has not
been handled.
* pph-streamer-out.c (pph_out_tcc_declaration): Factor out of
pph_write_tree_body. Handle all decls.
(pph_out_tcc_type): Factor out of pph_write_tree_body. Handle
all types.
(pph_write_tree_body): Issue a fatal error if a node has not
been handled.
