Dan Gohman 205b641954 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the
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.

; Make sure the uint isn't removed. Instcombine in llvm 1.9 was dropping the
; uint cast which was causing a sign extend. This only affected code with
; pointers in the high half of memory, so it wasn't noticed much
; compile a kernel though...
