Likewise, there is no autoconf magic for this. I killed it.

Ok. I'm trying to decide where the cleanest place to slot the lib in
so it can conditionally be part of Support. I'm thinking of something
like putting it in lib/Support/Regex, which would only be part of the
build if needed, and would compile to LLVMSupportRegex which
llvm-config would know to add to the link line. Chris, does this seem
ok?
