Change unused_labels from allow to warn
Fixes #66324, making the unused_labels lint warn instead of allow by default. I'm told @rust-lang/lang will need to review this, and perhaps will want to do a crater run.

Deleted unused labels from compiler and fixed or allowed
unused labels in tests. This patch removes some gratuitous
unused labels and turns off the warning for unused labels
that are a necessary part of tests. This will permit
setting the `unused_labels` lint to `warn`.
|
|
|
|
This change makes error and warning annotations mandatory in UI tests.
The only exception are tests that use error patterns to match compiler
output and don't have any annotations.

Re-enable Emscripten's exception handling support
Passes LLVM codegen and Emscripten link-time flags for exception
handling if and only if the panic strategy is `unwind`. Sets the
default panic strategy for Emscripten targets to `unwind`. Re-enables
tests that depend on unwinding support for Emscripten, including
`should_panic` tests.

Use heuristics to recover parsing of missing `;`
- Detect `,` and `:` typos where `;` was intended.
- When the next token could have been the start of a new statement,
detect a missing semicolon.
Fix #48160, fix #44767 (after adding note about statements).

Point at the span for the definition of ADTs internal to the current
crate.
Look at the leading char of the ident to determine whether we're
expecting a likely fn or any of a fn, a tuple struct or a tuple variant.
Turn fn `add_typo_suggestion` into a `Resolver` method.

Make the spacing between the code snippet and verbose structured
suggestions consistent with note and help messages.

- Compatible with Emscripten 1.38.46-upstream or later upstream.
- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the old incorrect wasm32 C call ABI with the correct one,
preserving the old one as wasm32_bindgen_compat for wasm-bindgen
compatibility.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.

This reverts commit 7870050796e5904a0fc85ecbe6fa6dde1cfe0c91, reversing
changes made to 2e7244807a7878f6eca3eb7d97ae9b413aa49014.

- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the incorrect wasm32 C call ABI with the old asmjs
version, which is correct for both wasm32 and JS.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Temporarily makes Emscripten targets use panic=abort by default
because supporting unwinding will require an LLVM patch.

Stabilize macros in some more positions
- Fn-like macros and attribute macros in `extern` blocks
- Fn-like procedural macros in type positions
- ~Attribute macros on inline modules~ (moved to https://github.com/rust-lang/rust/pull/64273)
Stabilization report: https://github.com/rust-lang/rust/pull/63931#issuecomment-526362396.
Closes https://github.com/rust-lang/rust/issues/49476

When declaring a declarative macro in an item it's only accessible inside it

Split off from #62855
This PR deerializes the declaration `Span` and attributes for all
procedural macros from their underlying function definitions.
This allows Rustdoc to properly render doc comments
and source links when inlining procedural macros across crates

Hygienize use of built-in macros in the standard library
Same as https://github.com/rust-lang/rust/pull/61629, but for built-in macros.
