Issue-125323: ICE non-ADT in struct pattern when long time constant evaluation is in for loop This PR fixes rust-lang#125323 ## Context According to the issue, the ICE happens since rust-lang#121206. In the PR, some error methods were reorganized. For example, has_errors() was renamed to has_errors_exclude_lint_errors(). However, some codes which used the original has_errors() were not switched to has_errors_exclude_lint_errors(). I finally found that report_error() in writeback.rs causes this ICE. Currently the method uses tainted_by_errors() to get guar (ErrorGuaranteed), but originally it used dcx().has_errors() but it wasn't changed to has_errors_exclude_lint_errors() when changes in rust-lang#121206 were merged. I don't think I fully understand how an error is propagated, but I suppose that the error from long time constant evaluation is unexpectedly propagated other parts (in this ICE, for loop), then cause the non-ADT in struct pattern ICE. ## Change - Fix report_error() in writeback.rs: use dcx().has_errors_exclude_lint_errors() instead of tainted_by_errors() to prevent error propagation from constant evaluation. - Add test for the ICE - Modify some tests to align the change: Due to this fix, E0282 error happens (or not happen anymore) in some tests. ## NOTE The 4th commit aims to revert the fix in rust-lang#123516 because I confirmed that the ICE solved by the PR doesn't happen if I modify report_error(). I think the root cause of that ICE is the same as rust-lang#125323 . But I can discard this commit since we can fix rust-lang#125323 without it.
