Dan Gohman f2f6ce65b7 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.

; Instcombine should not promote the mul to i96 because it is definitely
; not a legal type for the target, and we don't want a libcall.
