If there is one, I do not know of it.

My method for determining which library to link is twofold:

1) Since I have a general understanding of LLVM's libraries, I can make 
educated guesses if I know what the pass does.  If it's an 
inter-procedural analysis pass, then it's in LLVMipa.  If it's something 
to do with code generation, then it's probably in LLVMCodeGen.  There's 
a list of the libraries at 
http://llvm.org/docs/UsingLibraries.html#descriptions.

2) If that doesn't work, I use xargs/grep to search the source base for 
the class's implementation.  I then look at the Makefile in the same 
directory to figure out which library it's being compiled into.

I know this may not seem convenient, but it actually works pretty well, 
and the longer you work with LLVM, the easier it gets.
