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

; RUN: opt < %s -instcombine -S | grep {ret i1 false} | count 2
"ret (constexpr)" can't be folded into a Constant. Add a method to Analysis/ConstantFolding to fold ConstantExpr's, then make instcombine use it to try to use targetdata to fold constant expressions on void instructions. Also extend the icmp(inttoptr, inttoptr) folding to handle the case where int size != ptr size. llvm-svn: 51559
