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. llvm-svn: 81537 2009-09-11 18:01:28 +00:00			`; RUN: opt < %s -instcombine -S \| grep icmp \| count 1`
Reinstate this optimization, but without the miscompile. Thanks to Bill for tracking down that this was breaking llvm-gcc bootstrap on Linux. llvm-svn: 54394 2008-08-06 04:54:03 +00:00			`; PR2330`
