One difference from debugserver and lldb-server is that lldb-server provides "vg" and "svg" registers (vector granule, streaming vector granule, depending on Streaming mode) which is the vector length in 8-byte granules.  On Darwin, debugserver provides only "svl", in bytes.  I considered having debugserver report the vector length in granules to match the Linux behavior, but the kernel was giving me the value in bytes and I think it's a more natural representation, so I stuck with it.
