Esteban Küber f0b8e13b59 Do not suggest using -Zmacro-backtrace for builtin macros
For macros that are implemented on the compiler, we do *not* mention the `-Zmacro-backtrace` flag. This includes `derive`s and standard macros.

error[E0277]: the trait bound `PartialEqNotEq: Eq` is not satisfied
--> $DIR/union-derive-eq.rs:21:5

LL | #[derive(Eq)]

LL | union U2 {
LL | a: PartialEqNotEq,
| ^^^^^^^^^^^^^^^^^ the trait `Eq` is not implemented for `PartialEqNotEq`

note: required by a bound in `AssertParamIsEq`
--> $SRC_DIR/core/src/cmp.rs:LL:COL
help: consider annotating `PartialEqNotEq` with `#[derive(Eq)]`

LL + #[derive(Eq)]
