This is version 4 of perf builtin clang and perfhook patch series.
In this patch set:
1. Cleanup options passed to clang.
2. Check LLVM version. Fail if llvm version < 3.9.0, and
warn when it > 3.9.0. More version will be allowed after
releasing of LLVM 3.9.1 / 4.0.0.
3. Support dynamic linking LLVM and clang libraries.
4. Rebase to Arnaldo's newest perf/core.
