This PR adds a note to the end of the Windows build instructions to reflect the issues detailed in #28260, as well as a work around using older versions of gcc. I've avoided going into detail as I did not wish to bloat the README, and so that the changes are easy to yank once the issue is resolved.
PR for #28157. At the moment, `rustc` emits a warning when a bare semicolon is encountered (could also be a fail, but I think this is a backwards incompatible change).
Also I am not sure where the best place for a test for that warning would be. Seems run-pass tests do not check warnings.
Give preference to projections from where-clauses over those from trait definitions. This makes #28871 work again, though I think there's more to fix in this general area.

The new bots we have may conflict with one another on base ports, causing tests
to fail. For example the linux-musl-64-opt and linux-64-opt bots are using the
same base port right now, causing some spurious failures every now and then.
Fixes#29184
This adds an error message for the use of the reserved `typeof` keyword, instead of reporting an ICE.
Also adds a `compile-fail` test.
I chose to add a `span_err` instead of removing to parser code, as to preserve the reservation of `typeof`.
It's possible that there is some meaning I'm not grasping from the headers "Traits bounds for generic functions" and "Traits bounds for generic structs", but they seem to me like they could be clearer and more grammatically correct.
Qualified paths allow full path after the `>::`. For example
```rust
<T as Foo>::U::generic_method::<f64>()
```
The example is taken from `test/run-pass/associated-item-long-paths.rs`.
It looks like the target libs aren't actually the same across hosts so instead
of always packaging the target libs from CFG_BUILD take the target libs from the
host if we have them and then only failing that do we take them from CFG_BUILD.
Closes#29228
{BTree,Hash}{Map,Set} will not update their key if it already exists, which
can matter with more complex keys. This behavior is now documented.

The example is taken from `test/run-pass/associated-item-long-paths.rs`.
Currently it is possible to do the following:
- define a module named `Foo` and then a unit or tuple struct also named `Foo`
- define any struct named `Foo` and then a module named `Foo`
This commit introduces a warning for both of these cases.
trait definitions, and give prefence to the former. This is consistent
with what we do for selection. It also works around a limitation
that was leading to #28871.
