Those aren't really interesting, however outputting them is helpful when
trying to feed the IR to llvm llc (or opt) for debugging.

It's not a bad idea to dump intrinsics and other functions.
But for the record, the most robust way of getting the whole IR (to pass
to llc/opt) is to dump it to file:

LLVMWriteBitcodeToFile(gallivm->module, "llvmpipe.bc");
debug_printf("llvmpipe.bc written\n");
debug_printf("Invoke as \"llc -o - llvmpipe.bc\"\n");
But I agree it should be easier to do this (there should be an
GALLIVM_DEBUG option for this). Also this code was written when there
was a single module -- instead of llvmpipe.bc we should use something
derived from module name so each module go to its own file.
