It was assumed in hipe_icode_fp:filter_map/3 that either all
predecessors would have an up-to-date ("assigned") tagged copy, or none
of them.
This is temporarily false during the fixpoint loop in
basic_floats:test_icode_type_crash_2/0, which exercises the
all_args_equal(Bindings) =:= true branch, that would previously
erroneously end up in the 'false' branch, which is what caused the crash
in that case.
This is likewise only temporarily false during the fixpoint loop in
basic_floats:test_icode_type_crash/0, but that case instead exercises
the 'false' branch, justifying the inclusion of both tests.

The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(),
set(), and tid() have been deprecated. They will be removed in OTP 18.0.
Instead the types array:array(), dict:dict(), digraph:graph(),
gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid()
can be used. (Note: it has always been necessary to use ets:tid().)
It is allowed in OTP 17.0 to locally re-define the types array(), dict(),
and so on.
New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2,
queue:queue/1, and sets:set/1 have been added.
