    It seems that some Apple LLVM wrappers emit multiple messages containing
    the string "version", which we previously used to find the version
    number.  For instance,
        Configured with: --prefix=/Applications/Xcode.app/Contents/...
        Apple LLVM version 9.0.0 (clang-900.0.37)
        Target: x86_64-apple-darwin16.7.0
        Thread model: posix
        InstalledDir: /Applications/Xcode.app/Contents/Developer/...
        Found CUDA installation: /usr/local/cuda, version 8.0
    We now take care to only look at the first occurrence of this string.
    New `sed` command due to @merijn.
    Test Plan: Validate on all the compilers
