[PATCH, applied] ir: Make IR node visitor aware of non-canonicalized types

[Dodji Seketeli]

Hello,

is_non_canonicalized_type is the function that decides which type
should be canonicalized or not.  So, code that expects a type to be
canonicalized should comply with the rule of
is_non_canonicalized_type, aka The Rule.  It turns out, the IR node
visitor code fails to comply with The Rule.  Fixed thus.  Note that
with this commit, the program build/tests/testirwalker now works fine
on itself.  Many thanks to Cestmir Kalina who noticed and reported the
issue.

	* src/abg-ir.cc (ir_node_visitor::{mark_type_node_as_visited,
	type_node_has_been_visited}): Invoke is_non_canonicalized_type to
	know if we should expect a type to have a canonical type or not.

Applied to the master branch.
