Most importantly, this version of delocate works for ppc64le. It should also work for x86-64, but will need significant testing to make sure that it covers all the cases that the previous delocate.go covered. It's less stringtastic than the old code, however the parser isn't as nice as I would have liked. I thought that the reason we put up with AT&T syntax with Intel is so that assembly syntax could be somewhat consistent across platforms. At least for ppc64le, that does not appear to be the case.
