Esteban Küber 37c54db477 Silence some resolve errors when there have been glob import errors
When encountering `use foo::*;` where `foo` fails to be found, and we later
encounter resolution errors, we silence those later errors.

A single case of the above, for an *existing* import on a big codebase would
otherwise have a huge number of knock-down spurious errors.

Ideally, instead of a global flag to silence all subsequent resolve errors,
we'd want to introduce an unameable binding in the appropriate rib as a
sentinel when there's a failed glob import, so when we encounter a resolve
error we can search for that sentinel and if found, and only then, silence
that error. The current approach is just a quick proof of concept to
iterate over.

Partially address #96799.

// This checks that a path that cannot be resolved because of an indeterminate import
// does not trigger an ICE.
mod foo {
pub use self::*; //~ ERROR unresolved
}
fn main() {
foo::f(); // cannot find function `f` in module `foo`, but silenced
}
