Rollup merge of #131080 - alexcrichton:stabilize-more-wasm-target-features, r=petrochenkov
Stabilize WebAssembly `multivalue`, `reference-types`, and `tail-call` target features

For the `multivalue` and `reference-types` features this commit is
similar to https://github.com/rust-lang/rust/pull/117457 in that it's stabilizing target features specific to
WebAssembly targets. The previous PR left out these two features because
they weren't expected to change much about compiled code so it was
unclear what the rationale was. It has [since been discovered][blog]
that `reference-types` can be useful as it changes the binary format of
the `call_indirect` instruction. Additionally [on Zulip][zulip] there's
a use case of detecting these features at compile time and generating a
compile error to better warn users about features not supported on
engines.

This PR then additionally adds the `tail-call` feature which corresponds
to the [tail-call] proposal to WebAssembly. This feature advanced to
"phase 4" in the WebAssembly CG awhile back and has been supported in
LLVM for quite some time now. Engines are finishing up implementations
or have already shipped implementations, so while this is a bit of a
late addition to Rust itself it reflects the current status of
WebAssembly's state of the feature.

A test has been added here not only for these features but other
WebAssembly features as well to showcase that they're usable without
feature gates in stable Rust.

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>.
