Update the-stack-and-the-heap.md
Was surprised to learn that heaps were used in this way, then realized upon reading [the linked paper](http://www.cs.cmu.edu/afs/cs/academic/class/15213-f98/doc/dsa.pdf) that it's a totally different type of heap—an important distinction.
Provide more explicit example of wildcard version in guessing game doc.
Beginners may try to adapt the tutorial to develop their own code.
When using different dependencies, they may use the wildcard for
versioning. Since they are new to the language, they will not know
that the wildcard asterisk is a string, not a token. Make the correct
format more explicit, to remove one potential source of frustration.

Properly feature gate all unstable ABIs

Function-visiting machinery for AST/HIR is surprisingly error-prone, it's *very* easy to miss some cases or visit something twice while writing a visitor. This is the true problem behind https://github.com/rust-lang/rust/issues/34900. I'll try to restructure these visitors a bit and send one more PR later.
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!() }
```
