To sum up:
With `std::move` it's 1 copy 1 move for lvalue or 1 move for rvalue
With `const&` it's 1 copy for lvalue or rvalue
small repro https://godbolt.org/z/EosczKoo7
For me it this patch adds inconsistency for the check: if we have
```cpp
void NegativeMoved(ExpensiveToCopyType A) {
ExpensiveToCopyType Copy = std::move(A); // no warning
}
```
then I remove `std::move`, I'd expect the check to suggest it, but now it wants
`const&`
