There is a tool called Revgen which might do what you need, though I 
don't know if it meets your needs.  Revgen can translate native code to 
LLVM IR, but I'm not sure if it can translate the LLVM IR back to native 
code for execution.

There is also s2e which does dynamic translation from binary code to 
LLVM IR; it should be able to run the code after instrumentation.

IIRC, both come from George Candea's group at EPFL.  A quick Google 
search should help you find the code.
