Description

I have LLVM 7.1 installed locally, and FindClangTools couldn't locate it because ARROW_LLVM_VERSION is hardcoded to 7.0 and clang tools is restricted to the minor version.

If it makes sense to restrict clang tools location down to the minor version, then we need to pass the located LLVM's version instead of the hardcoded one.
