LLVM is the whole toolchain.  clang is a new front-end which produces
LLVM-IR (intermediate representation) directly.  llvm-gcc and the
in-development dragonegg GCC plug-in use the GCC parser, convert GCC's
IR to LLVM-IR, and then use LLVM's optimizer and code generator to
finish the job.

clang emulates the GCC CLI with fair accuracy, and of course llvm-gcc
and dragonegg use the GCC CLI directly.

I'm looking forward to debugging optimized code and getting sane
backtraces!
