I wouldn't go as far as saying that we "need" an IR-level debugger, but 
from my perspective it would be something that would help developers who 
use Clang/LLVM to debug their code.  At higher optimization levels in 
particular, source-level debugging may be obscured by various 
optimizations, and assembly-level debugging may be too tedious and cryptic.
