InstrProf: Test for appropriate linkage of the profiling structures This test checks that the symbols instrprof creates have appropriate linkage. The tests already exist in clang in a slightly different form from before we sunk profile generation into an LLVM pass, but that's an awkward place for them now. I'll remove/simplify the clang versions shortly. llvm-svn: 230383
