Rollup merge of #129760 - cuviper:old-timey, r=compiler-errors 
Make the "detect-old-time" UI test more representative

The test code did have an inference failure, but that would have failed
on Rust 1.79 and earlier too. Now it is rewritten to be specifically
affected by 1.80's `impl FromIterator<_> for Box<str>`.

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and intepret a test.

As part of an on-going effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

An example directive is ignore-test. In legacy compiletest style, the header would be written as

// ignore-test

but in ui_test style, the header would be written as

//@ ignore-test

compiletest is changed to accept only //@ directives for UI tests (currently), and will reject and report an error if it encounters any comments // <content> that may be parsed as an legacy compiletest-style test header. To fix this, you should migrate to the ui_test-style header //@ <content>.
