[PATCH] D37920: Resubmit (Fixed) "[lit] Force site configs to be run before source tree configs"

[Zachary Turner via Phabricator via llvm-commits]

Incorporated suggestions from beanz@ offline.  Specifically, the concern is that someone could download and install lit via a package manager, but we would still try to add an out of tree source directory.  This update makes it so that we generate `llvm-lit` iff a source tree is available, and we *use* the generated `llvm-lit` whenever `-DLLVM_EXTERNAL_LIT` is not specified.
