Stop passing -export-dynamic to wasm-ld.

-export-dynamic was a temporary hack added in the early days of the Rust wasm32 target when Rust didn't have a way to specify wasm exports in the source code. This flag causes all global symbols, and some compiler-internal symbols, to be exported, which is often more than needed.

Rust now does have a way to specify exports in the source code: `#[export_name = "..."]`.

So as the original comment suggests, -export-dynamic can now be removed, allowing users to have smaller binaries and better encapsulation in their wasm32-unknown-unknown modules.

It's possible that this change will require existing wasm32-unknown-unknown users will to add explicit `#[export_name = "..."]` directives to exporrt the symbols that their programs depend on having exported.

This is based on top of https://github.com/rust-lang/rust/pull/105301. Only the last two commits are new.

While investigating https://github.com/rust-lang/unsafe-code-guidelines/issues/381 I realized that we would have caught this issue much earlier if the add_retag pass wouldn't bail out on assignments of the form `*ptr = ...`.

So this PR changes our retag strategy:
- When a new reference is created via `Rvalue::Ref` (or a raw ptr via `Rvalue::AddressOf`), we do the retagging as part of just executing that address-taking operation.
- For everything else, we still insert retags -- these retags basically serve to ensure that references stored in local variables (and their fields) are always freshly tagged, so skipping this for assignments like `*ptr = ...` is less egregious.

rustdoc: clean up docblock table CSS

* The rule `display: block` had no noticeable effect. Technically, because
  markdown tables have a tbody and thead, they get wrapped in an [anonymous
  table box] in the CSS tree, nested within the `<table>` element's block
  layout box.

  This rule was added in #87230 to make the table side-scrolling, but
  this same issue was doubly fixed in #88742 by wrapping it in an explicit
  `<div>` tag. Since accessibility advocates recommend the wrapper div over
  marking the table as `display: block`, we'll stick with that.

  https://adrianroselli.com/2020/11/under-engineered-responsive-tables.html

* The rule `width: calc(100% - 2px)` had no visible effect, because the
  anonymous table box was not affected.

* The style is tweaked to basically be the same style GitHub uses.

Pass on null handle values to child process

Fixes #101645

In Windows, stdio handles are (semantically speaking) `Option<Handle>` where `Handle` is a non-zero value. When spawning a process with `Stdio::Inherit`, Rust currently turns zero values into `-1` values. This has the unfortunate effect of breaking console subprocesses (which typically need stdio) that are spawned from gui applications (that lack stdio by default) because the console process won't be assigned handles from the newly created console (as they usually would in that situation). Worse, `-1` is actually [a valid handle](https://doc.rust-lang.org/std/os/windows/io/struct.OwnedHandle.html) which means "the current process". So if a console process, for example, waits on stdin and it has a `-1` value then the process will end up waiting on itself.

This PR fixes it by propagating the nulls instead of converting them to `-1`.

While I think the current behaviour is a mistake, changing it (however justified) is an API change so I think this PR should at least have some input from t-libs-api. So choosing at random...

Dan Gohman [Wed, 7 Dec 2022 00:50:29 +0000 (16:50 -0800)]
Stop passing -export-dynamic to wasm-ld.

-export-dynamic was a temporary hack added in the early days of the Rust
wasm32 target when Rust didn't have a way to specify wasm exports in the
source code. This flag causes all global symbols, and some compiler-internal
symbols, to be exported, which is often more than needed.

Rust now does have a way to specify exports in the source code:
`#[export_name = "..."]`.

So as the original comment suggests, -export-dynamic can now be removed,
allowing users to have smaller binaries and better encapsulation in
their wasm32-unknown-unknown modules.

It's possible that this change will require existing wasm32-unknown-unknown
users will to add explicit `#[export_name = "..."]` directives to
exporrt the symbols that their programs depend on having exported.
