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.

; This test lets globalopt split the global struct and array into different
; values. This used to crash, because globalopt forgot to put the new var in the
; same address space as the old one.
; RUN: opt < %s -globalopt -S > %t
; Check that the new global values still have their address space
; RUN: cat %t | grep global.*addrspace
