Subject: [PATCH 1/3] [Dexter] Write expects for variables in Debugger scopes
Following on from the previous patch, this patch adds support for writing
expects from !value/all nodes, generating separate expects for each
variable in the requested debugger scope, for each continuous range of lines
it is live for.
