Information on using LLVM can be found on the Documentation page on the 
LLVM web site (http://llvm.org/docs/).  The "Getting Started Guide" 
provides information on how to build LLVM and gives a simple example on 
how to compile a program using LLVM.

LLVM is a compiler *infrastructure.*  You can use it to build program 
analysis tools, compilers, JITs, and many other tools.  Some people 
(including the people who wrote the paper you mentioned) use LLVM to 
build prototype testing tools.  Some people integrate their code into 
the LLVM project, some give their code away as separate modules that 
work with LLVM, and some people don't release their code at all.

As far as I know, the authors of the paper you mentioned have not 
contributed their code to the LLVM project.  You will need to contact 
the authors of that paper and ask them if they are willing to give you a 
copy of their code.  If they're not willing to give you a copy of their 
code, then you will need to implement their tool on your own.
