PPC64 target. The five tests modified herein test code generation that is sensitive to the code model selected. So I've added -code-model=small to the RUN commands for each. Since small code model is the default, this has no effect for now; but this prepares us for eventually changing the default to medium code model for PPC64. Test changes verified with small and medium code model as default on powerpc64-unknown-linux-gnu. All tests continue to pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167999 91177308-0d34-0410-b5e6-96231b3b80d8
