bors f6648f252a Auto merge of #126557 - GrigorenkoPV:vec_track_caller, r=joboet
Add `#[track_caller]` to allocating methods of `Vec` & `VecDeque`

Part 4 in a lengthy saga.
r? `@joshtriplett` because they were the reviewer the last 3 times.
`@bors` rollup=never "[just in case this has perf effects, Vec is hot](https://github.com/rust-lang/rust/pull/79323#issuecomment-731866746)"

This was first attempted in #79323 by `@nvzqz.` It got approval from `@joshtriplett,` but rotted with merge conflicts and got closed.

Then it got picked up by `@Dylan-DPC-zz` in #83359. A benchmark was run[^perf], the results (after a bit of thinking[^thinking]) were deemed ok[^ok], but there was a typo[^typo] and the PR was made from a wrong remote in the first place[^remote], so #83909 was opened instead.

By the time #83909 rolled around, the methods in question had received some optimizations[^optimizations], so another perf run was conducted[^perf2]. The results were ok[^ok2]. There was a suggestion to add regression tests for panic behavior [^tests], but before it could be addressed, the PR fell victim to merge conflicts[^conflicts] and died again[^rip].

3 years have passed, and (from what I can tell) this has not been tried again, so here I am now, reviving this old effort.

Given how much time has passed and the fact that I've also touched `VecDeque` this time, it probably makes sense to
`@bors` try `@rust-timer`

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>.
