[PATCH] [LIT] Allow suite configs to be preloaded allowing for better support of out-of-dir builds.

[Eric Fiselier]

It just seemed like an ugly patch and the wrong way to do things. As you mentioned both clang and LLVM already provide similar functionality at almost no extra cost compared to this patch. For that reason it doesn't make sense to dirty up lit to achieve these goals.
