Comment (by rrnewton):
Sorry, I was just referring to the proposal to "substitute the cas funcall
with the right llvm operation" as rewriting.
That is, the approach would pattern match for the CMM code "ccall cas" or
"foreign "C" cas" (I'm afraid I don't know the difference between those)
and replace it with the equivalent LLVM op, right?
