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.

{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.

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.
When reading this paragraph, the beginning Rust programmer is starting
to write a Hello World program. We have just told her to name the file
`main.rs`, and immediately afterward, a `hello_world.rs` is mentioned.
I changed this to an unrelated filename (incidentally one that appears
in this repository) to make it clear that this is just an example.
Also, wording it as a declarative sentence rather than an imperative one
further separates it from the Hello World instructions in this section.

(Let me know if I'm sending too many PRs -- I can batch up TRPL edits, say, per chapter, if that works better. Or I can just refrain from editing TRPL as I read through it, if these are not sufficiently useful.)
Adds the pacman git command to the high level Windows installation instructions. As the MSYS2 installation may not include Windows git on the path by default (based on the path settings of Windows users), I figured this could be a helpful inclusion.
The paragraph here seemed confusing, so I reworded it. Also added
another possible reason why `curl | sh` might be objectionable to users.

This is a pretty trivial change. My eye caught some inconsistent whitespace while perusing compiler errors tonight. Specifically, I changed `//correct` to `// correct`, and got rid of some trailing whitespace that isn't seen in other code snippets.
This commit expands the "supported platforms" section of the book to include
documentation on the tiers that Rust currently has as well as organizing all
supported platforms into these various tiers. Infrastructure improvements over
the next few months are likely to change the location of may of these platforms
over, but for now this should faithfully represent what we've got today!
