In a piece of DSP code, our LLVM-based compiler was able to
convert a small temporary array into a set of scalar variables,
which subsequently ended up in registers. So at least LLVM is
able to do this today. I would be somewhat surprised if gcc
were not capable of doing similar things.

I am not entirely convinced that using pointer arithmetic
instead of array subscripting would make much difference here
though, but I am not a C expert by any means.
