I think you may be referring to the "clang" compiler front-end, not LLVM per se:

http://clang.llvm.org/

I believe it is possible to build MacRuby with clang, though we don't take advantage of any clang-specific features since Ruby by default builds with -c99 strict mode.  Clang is only about compile-time diagnostics and static analysis for C code, which is useful for people debugging the underlying implementation but not of general interest.

In terms of performance, the important aspect is the LLVM back-end, which I believe we have always used.
