This is a resubmission of r313270. It broke standalone builds of compiler-rt because we were not correctly generating the llvm-lit script in the standalone build directory. The fixes incorporated here attempt to find llvm/utils/llvm-lit from the source tree returned by llvm-config. If present, it will generate llvm-lit into the output directory. Regardless, the user can specify -DLLVM_EXTERNAL_LIT to point to a specific lit.py on their file system. This supports the use case of someone installing lit via a package manager. If it cannot find a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or invalid, then we print a warning that tests will not be able to run.
