...
In preparation for "experimental-async-fn" as a completely orthogonal
experimental feature.

Avoid inheriting formatter flags in some Display impls
...
The previous implementation would produce wrong unintentional output
when formatting with alignment or padding, such as {:<15}.

Remove check for duplicated discriminants
...
C++ enum and enum class are allowed to contain multiple enumerator
definitions with the same value. Our enum representation in Rust is
compatible with this too, so there is no need to error on such enums.
enum class Enum {
A = 5,
B = 4,
C = 4, // dup
D, // = 5 dup
};
