f3e6d31538 Auto merge of #28351 - jonas-schievink:macro-bt, r=nrc
The second commit in this PR will stop printing the macro definition site in backtraces, which cuts their length in half and increases readability (the definition site was only correct for local macros).

The third commit will not print an invocation if the last one printed occurred at the same place (span). This will make backtraces caused by a self-recursive macro much shorter.

(A possible alternative would be to capture the backtrace first, then limit it to a few frames at the start and end of the chain and print `...` inbetween. This would also work with multiple macros calling each other, which is not addressed by this PR - although the backtrace will still be halved)

Example:
```rust
macro_rules! m {
 ( 0 $($t:tt)* ) => ( m!($($t)*); );
 () => ( fn main() {0} );
}

m!(0 0 0 0 0 0 0 0 0 0 0 0 0 0 0);
```

On a semi-recent nightly, this yields:
```

This patch transforms functions of the form
```
fn f<Generic: AsRef<Concrete>>(arg: Generic) {
	let arg: &Concrete = arg.as_ref();
	// Code using arg
}
```
to the next form:
```
#[inline]
fn f<Generic: AsRef<Concrete>>(arg: Generic) {
	fn f_inner(arg: &Concrete) {
		// Code using arg
	}
	
	f_inner(arg.as_ref());
}
```

Therefore, most of the code is concrete and not duplicated during monomorphisation (unless inlined)
and only the tiny bit of conversion code is duplicated. This method was mentioned by @aturon in the
Conversion Traits RFC (https://github.com/rust-lang/rfcs/blame/master/text/0529-conversion-traits.md#L249) and similar techniques are not uncommon in C++ template libraries.

This patch goes to the extremes and applies the transformation even to smaller functions<sup>1</sup>
for purity of the experiment. *Some of them can be rolled back* if considered too ridiculous.

<sup>1</sup> However who knows how small are these functions are after inlining and everything.

The functions in question are mostly `fs`/`os` functions and not used especially often with variety
of argument types, so the code size reduction is rather small (but consistent). Here are the sizes
of stage2 artifacts before and after the patch:
https://gist.github.com/petrochenkov/e76a6b280f382da13c5d
https://gist.github.com/petrochenkov/6cc28727d5256dbdfed0

Note:
All the `inner` functions are concrete and unavailable for cross-crate inlining, some of them may
need `#[inline]` annotations in the future.

7f5ec6c392 Disable browser history API on file:/ URLs
history.pushState is defined, but not working whenever document.origin is "null"
(literally that string, not just the null object).
This is due to some security considerations and is unlikely to be ever working.

For now just disable the usage of the history API when the documentation
is accessed through a file:/ URL.

See https://code.google.com/p/chromium/issues/detail?id=301210 for a
Chrome-specific issue on the history API on file:/ URLs
