Title: llvm_version check.

Don't trip up in the clang_version and llvm_version check if LLVM_COMPILER points to a directory that is a SDK build directory containing only packaged binary llvm tools.

If the directory tree for used LLVM compiler is not from a LLVM source checkout and clang_version is not found, assume clang_version = llvm_version.
