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.
