Fix pr11266. On x86: (shl V, 1) -> add V,V Hardware support for vector-shift is sparse and in many cases we scalarize the result. Additionally, on sandybridge padd is faster than shl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143311 91177308-0d34-0410-b5e6-96231b3b80d8 2011-10-30 13:24:22 +00:00			`; RUN: llc < %s -march=x86 -mcpu=corei7 \| FileCheck %s`

Update to more CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change.
