Migration: add isCompound parameter to FixBuilder.visitAssignmentTarget.

When visiting an assignment target that is an index expression
(`x[y]`) we'll need to know whether we are doing a compound assignment
or not, because this will influence whether the type context for the
index expression (`y`) should come from `operator[]` or `operator[]=`.

So before adding index expression support to FixBuilder, let's add an
`isCompound` boolean to indicate whether the assignment context is a
compound assignment or not.
