This is 682889f but for tuples. The
reasoning is the same:

* This commit also changes it so that tuples with all-generic elements still
  link to the primitive.tuple.html page, just like slices. So there still
  plenty of on-ramps for anybody who doesn't know about it.
* It's too hard to see when round braces are a separate link from the type
  inside of them.
* It's too hard to click even if you do notice them.
rust-lang#93227 liberated late bound regions when collecting GAT substs in wfcheck.  It should simply skip late bound regions instead.

rustdoc: remove tuple link on round braces

This is rust-lang#98069 but for tuples. The reasoning is the same:

* This PR also changes it so that tuples with all-generic elements still link to the primitive.tuple.html page, just like slices. So there still plenty of on-ramps for anybody who doesn't know about it.
* It's too hard to see when round braces are a separate link from the type inside of them.
* It's too hard to click even if you do notice them.

Remove --memory-init-file flag when linking with Emscripten

This flag does nothing. It only applies when generating asmjs JavaScript.

Skip late bound regions in GATSubstCollector

Remove accidental uses of `&A: Allocator`

Cc rust-lang#98232

Fixes rust-lang#98176 (for real this time)
Write help for unexpected `=>`. Fixes rust-lang#98128

rust-lang#98128 discusses what to do with the typo `=>` vs `>=`, or efforts to write a JavaScript-syntax closure in Rust (`(a, b) => (a + b)`). Both manifest as an unexpected `token::FatArrow` so the error message describes both. I think that only those who are very new to programming would actually need to be told how to spell `>=`, but I could understand someone misreading the existing error message and not realising what they'd typed. The opposite of this is:
```
(a, b) =< (a + b);
                 ^ expected one of `>` or `as`
```
which I think would be significantly more complex to detect because `=<` isn't a token, and less beneficial as I'm not aware of a language which actually uses that syntax for something.
