Fix partial DFG conversion of concat assignments (#6255) 
When we had a `{a, b} = ...`, and the DFG conversion of `a = ...`
succeeded, but `b = ...` failed, we still used to include `a = ...` in
the DFG, which then caused a spurious multi-driver error for `a` on
a subsequent DFG pass, as the original `{a, b} = ...` was still present
in the Ast, but we also had the extra `a = ...` from converting out of
DFG on the previous pass.

In this patch we only convert assignments with a concatenation on the
LHS, if all target LValues can be converted into DFG.

This is the proper fix for #4231
