[PATCH] D38859: [clang] Enable clang build with LLVM_BUILD_INSTRUMENTED without setting LLVM_PROFTDATA

yeah, i agree, this is not a good idea. My thoughts were different - right now it's not particularly convenient that one has to specify LLVM_PROFDATA when it's not actually used by the build.
Maybe we can create the target "generate-profdata" only if LLVM_PROFDATA is set (but don't fail otherwise) ?
