Fix up documentation around no_std
1. Fix the sections in the book to have the correct signatures. I've
also marked them as `ignore`; there's no way to set the `no_std`
feature for libc, so it pulls in the stdlib, so this wasn't even
testing the actual thing it was testing. Better to just ignore.
2. Correcting libcore's docs for factual inaccuracy, and add a note
about language items.
Fixes#33677

The referenced code https://github.com/thestinger/rust-snappy can not work. Maybe it's the old rust version? I do not know.
So I try to rewrite these test cases. If it is not what you originally meaning, just ignored it.
Fix bugs in macro-expanded statement parsing
Fixes#34543.
This is a [breaking-change]. For example, the following would break:
```rust
macro_rules! m { () => {
println!("") println!("")
//^ Semicolons are now required on macro-expanded non-braced macro invocations
//| in statement positions.
let x = 0
//^ Semicolons are now required on macro-expanded `let` statements
//| that are followed by more statements, so this would break.
let y = 0 //< (this would still be allowed to reduce breakage in the wild)
}
fn main() { m!() }
```

Correct inline assembly clobber formatting.
Fixes the formatting for inline assembly clobbers used in the book.
As this causes llvm to silently ignore the clobber an error is also
added to catch cases in which the wrong formatting was used.
Additionally a test case is added to confirm that this error works.
This fixes#34458
Note: this is only one out of a few possible ways to fix the issue
depending on how the asm! macro formatting is wanted.
Additionally, it'd be nicer to have some kind of test or feedback
from llvm if the clobber constraints are valid, but I do not know
enough about llvm to say if or how this is possible.
Fix spacing in for loop enumeration example
Add a space between the comma and j in (i, j) to make it look nice.
This addresses my recent issue #34624.

update cargo doc link
updated proper link of cargo doc that contains details about list of options available in semantic versioninig for the dependencies section in Cargo.toml
update documentation of tuple/unit structs
I made the "tuple structs are useless" editorializing a bit weaker and moved it to the end. Feel free to overrule me on that.
I also added an example of how to unpack a tuple struct with dot notation, because it came up on IRC.
`braced_empty_structs` is stable now, so I updated the example for unit-like structs to use that syntax. Should we show both ways?

Book: Small grammatical and stylistic edits to book
I've been reading [the book](https://doc.rust-lang.org/book/) and noticed a few small grammatical and stylistic issues which I've rolled into this pull request.
I'm not sure if I should do so many small, unrelated edits in a single pull request but it seems like a lot of overhead for each small edit. Maybe one commit per edit but one pull request per file/section? Feedback is very much appreciated as this is my first pull request ever!
