Cycles:

* GPU kernel can now be compiled without __NON_PROGRESSIVE__ again, was broken after my last commit. Also add a check for have_error(), in case the GPU kernel comes without Non-Progressive, to avoid a crash.

* Don't compile progressive kernel twice on CPU, if __NON_PROGRESSIVE__ would be disabled there.
