manner. The chain operands are selected after all other nodes are selected. Uses
of chain nodes are modified after instruction selection is completed.

+Another instruction selector deficiency:
+
+void %bar() {
+ %tmp = load int (int)** %foo
+ %tmp = tail call int %tmp( int 3 )
+ ret void
+}
+
+_bar:
+ subl $12, %esp
+ movl L_foo$non_lazy_ptr, %eax
+ movl (%eax), %eax
+ call *%eax
+ addl $12, %esp
+ ret
+The current isel scheme will not allow the load to be folded in the call since
+the load's chain result is read by the callseq_start.
