I haven't double checked the sizeofs but it covers all the things in the
frame and like I said before there's no exclusion between PSTATE.{SM,ZA}.
I do think this should be clearer about what it's supposed to be
tracking.

I'd just say VL is the vector length, that's the term the architecture
uses and it says it's set with PR_SVE_SET_VL to clarify.
