I'm not sure. I don't know of any that have switched to llvm.

The Mesa OpenGL stack is apparently switching to use LLVM. Also, llvm-
gcc is opensource and produces large assembly files for large programs.
It's hard to know exactly what you're asking for here... I suspect it
comes down to having to benchmark the specific thing you're interested
in to find out for sure.
