This adds some technical debt in form of using writeOrReadElement in
clients, which can be paid incrementally by migrating these places to
handling assignment like expressions one by one. Doing it all in one
CL was too much. But now the underlaying AST resolution will be
sound.
In the next breaking change we will remove
setAssignmentBackwardCompatibility(), so stop setting elements/types
for assignment targets.
