Fixes #123156

Rather than expanding to std::rt::begin_panic, the expansion is now to unreachable!(). The resulting behavior is identical. A test that previously triggered the same error as #123156 has been added to ensure it does not regress.

Avoid expanding to unstable internal method

Fixes rust-lang#123156

Rather than expanding to `std::rt::begin_panic`, the expansion is now to `unreachable!()`. The resulting behavior is identical. A test that previously triggered the same error as rust-lang#123156 has been added to ensure it does not regress.
