gccrs: Fix ICE when typechecking non-trait item when we expect one
We just had an assertion here for this case where we expect a trait.
This changes the assertion into error handling producing the correct
error code with fixit suggestion like rustc.
Fixes #2499
gcc/rust/ChangeLog:
* typecheck/rust-hir-trait-resolve.cc (TraitResolver::resolve_path_to_trait):
use error handling instead of assertion
* typecheck/rust-hir-type-check-item.cc (TypeCheckItem::visit): reuse trait reference
* typecheck/rust-hir-type-check-item.h: update prototype
gcc/testsuite/ChangeLog:
* rust/compile/nr2/exclude: nr2 cant handle this
* rust/compile/issue-2499.rs: New test.
