My (possibly faultly) understanding is that intel's has good support
for numerics, presumably through auto-vectorization and such, but only
works for intel's architectures and is only excellent on intel chips.
llvm-gcc is a temporary thing until clang can compile llvm.  GCC is
for when you don't want to use the llvm infrastructure, and just want
something easy to grab from the package manager.

In general, anyways.
