Subject: [PATCH] fix view bugs in vam/expr.Dequiet

Dequiet.rec panics on a vector.Named wrapping a vector.View, and it
returns a vector of the wrong length on a vector.View wrapping a
vector.Record with no fields.

(I didn't add any ztests here because I haven't been able to come up
with any that trigger these bugs.)
