input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8

; 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
|
