Guarantee trivial copy constructor and destructor for Str and Slice ...

Repro:

    const char *ptr(Str str) { return str.repr.ptr; }
    size_t len(Str str) { return str.repr.len; }

Before:

    ptr(Str):
        mov     rax, qword ptr [rdi]
        ret
    len(Str):
        mov     rax, qword ptr [rdi + 8]
        ret

After:

    ptr(Str):
        mov     rax, rdi
        ret
    len(Str):
        mov     rax, rsi
        ret
