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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230383 91177308-0d34-0410-b5e6-96231b3b80d8

InstrProf: Make the __llvm_profile_runtime_user symbol hidden This symbol exists only to pull in the required pieces of the runtime, so nothing ever needs to refer to it. Making it hidden avoids the potential for issues with duplicate symbols when linking profiled libraries together. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230566 91177308-0d34-0410-b5e6-96231b3b80d8

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786.
