Following should compile.
----
struct X
{
    int n;
    const void opAssign(const X rhs) {}
}
struct S
{
    int n;
    const(X) x;
}
void main()
{
    S s;
    s = s;
}
----
test.d(14): Error: variable test.main.s cannot modify struct with immutable
members
----

S has implicitly defined opAssign, but it does not call field x's opAssign.

Commit pushed to master at https://github.com/D-Programming-Language/dmd

https://github.com/D-Programming-Language/dmd/commit/b9896d14766fe5a067cf84d0d2c21418dfb35676
fix Issue 6216 - Built-in opAssign implicitly defined should call field's
opAssign

Separate 'top assignable' (see opAssign first) from 'blit assignable'
(memberwise), and now they are not related to 'modifiable' directly.
