Andreas Kling 732b39d120 LibJS: Don't evaluate computed MemberExpression LHS twice in assignments 
The following snippet would cause "i" to be incremented twice(!):

    let a = []
    let i = 0
    a[++i] += 0

This patch solves the issue by remembering the base object and property
name for computed MemberExpression LHS in codegen. We the store the
result of the assignment to the same object and property (instead of
computing the LHS again).
