Rollup merge of #64031 - Centril:param-attrs-no-macros-test, r=nikomatsakis 
Harden `param_attrs` test wrt. usage of a proc macro `#[attr]`

The `param-attrs-builtin-attrs.rs` test file uses the `#[test]` attribute which should cover this but `#[test]` isn't a proc macro attribute so we add another test to be on the safe side. This intends to address https://github.com/rust-lang/rust/pull/64010#issuecomment-526564316.

Allow checking of run-pass execution output in compiletest

Closes #63751
Adds a `check-run-results` flag to compiletest headers, which if enabled checks the output of the execution of a run-pass test's binary against expected output.

Rollup merge of #64104 - Mark-Simulacrum:intrinsic-fn-ptr-ice, r=estebank 
Emit error on intrinsic to fn ptr casts

I'm not sure if a type error is the best way of doing this but it seemed like a relatively correct place to do it, and I expect this is a pretty rare case to hit anyway.

dfd43f0fdd Auto merge of #63870 - estebank:async-fn-call, r=oli-obk 
Suggest call fn ctor passed as arg to fn with type param bounds

_Reviewer note: the relevant changes are in the second commit, the first is simple and mechanical, but verbose._

When forgetting to call a fn in an argument position to an fn that has a generic bound:

```rust
async fn foo() {}

fn bar(f: impl Future<Output=()>) {}

fn main() {
    bar(foo); // <- should be `bar(foo());`
}
```

suggest calling it:

```
error[E0277]: the trait bound `fn() -> impl std::future::Future {foo}: std::future::Future` is not satisfied
  --> $DIR/async-fn-ctor-passed-as-arg-where-it-should-have-been-called.rs:9:5
   |
LL | fn bar(f: impl Future<Output=()>) {}
   | --------------------------------- required by `bar`
...
LL |     bar(foo);
   |     ^^^ the trait `std::future::Future` is not implemented for `fn() -> impl std::future::Future {foo}`
   |
   = help: it looks like you forgot to use parentheses to call the function: `foo()`
```

Fix #63100. Follow up to #63833 and #63337.

7bb2d8b076 Slightly clean up the error for recursive async fn 
* Make it clear that type erasure is required, not just pointer
  indirection.
* Don't make the message specific to direct recursion.
