; When constant propogating terminator instructions, the basic block iterator
; was not updated to refer to the final position of the new terminator. This
; can be bad, f.e. because constproping a terminator can lead to the
; destruction of PHI nodes, which invalidates the iterator!
;
; Fixed by adding new arguments to ConstantFoldTerminator
;
