parser: Fix panic in 'const impl' recovery The panic happens when in recovery parsing a full `impl` (`parse_item_impl`) fails and we drop the `DiagnosticBuilder` for the recovery suggestion and return the `parse_item_impl` error. We now raise the original error "expected identifier found `impl`" when parsing the `impl` fails. Note that the regression test is slightly simplified version of the original repro in #81806, to make the error output smaller and more resilient to unrelated changes in parser error messages. Fixes #81806 2021-02-08 01:43:54 -06:00			`trait T { const`
			impl //~ ERROR: expected identifier, found keyword `impl`
			`}`

			`fn main() {}`
