The produced library would get a main shim too which conflicts with the
main shim of the executable linking the library.

Suggest copying trait associated type bounds on lifetime error Closes rust-lang#92033 Kind of the most simple suggestion to make - we don't try to be fancy. Turns out, it's still pretty useful (the couple existing tests that trigger this error end up fixed - for this error - upon applying the fix). r? `@estebank` cc `@nikomatsakis`

Add more info and suggestions to use of #[test] on invalid items
This pr changes the diagnostics for using `#[test]` on an item that can't be used as a test to explain that the attribute has no meaningful effect on non-functions and suggests the use of `#[cfg(test)]` for conditional compilation instead.
Example change:
```rs
#[test]
mod test {}
```
previously output
```
error: only functions may be used as tests
--> src/lib.rs:2:1
|
2 | mod test {}
| ^^^^^^^^^^^
```
now outputs
```
error: the `#[test]` attribute may only be used on a non-associated function
--> $DIR/test-on-not-fn.rs:3:1
|
LL | #[test]
| ^^^^^^^
LL | mod test {}
| ----------- expected a non-associated function, found a module
|
= note: the `#[test]` macro causes a a function to be run on a test and has no effect on non-functions
help: replace with conditional compilation to make the item only exist when tests are being run
|
LL | #[cfg(test)]
| ~~~~~~~~~~~~

…ds, r=estebank Do not ICE when inlining a function with un-satisfiable bounds Fixes rust-lang#93008 This is kinda a hack... but it's the fix I thought had the least blast-radius. We use `normalize_param_env_or_error` to verify that the predicates in the param env are self-consistent, since with RevealAll, a bad predicate like `<&'static () as Clone>` will be evaluated with an empty ParamEnv (since it references no generics), and we'll raise an error for it.
