instcombine: Migrate fprintf optimizations This patch migrates the fprintf optimizations from the simplify-libcalls pass into the instcombine library call simplifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168891 91177308-0d34-0410-b5e6-96231b3b80d8 2012-11-29 15:45:33 +00:00			`; RUN: opt < %s -instcombine -S \| FileCheck %s`
