When MSVC's `link.exe` wasn't found but another `link.exe` was, the error message given can be impenetrable to many users. The usual suspect is GNU's `link` tool. In this case, inform the user that they may need to install VS build tools. This only applies when Microsoft's link tool is expected. Not `lld-link` or other MSVC compatible linkers.
…ts, r=Amanieu Make `std::char` functions and constants associated to `char`. First step to fix rust-lang#71763.

…h-search-behaviour, r=kinnison Fix going back in history to a search result page on firefox This bug was actually firefox not re-running JS script when you go back in history. To trigger it on the current docs: * Make a search * Pick an element (which isn't on the same page as the current element!) * Go back in history Instead of having the search results, you'll see the normal doc page. You can find a small explanation about it [here](http://web.archive.org/web/20100428053932/http://www.firefoxanswer.com/firefox/672-firefoxanswer.html). r? @kinnison cc @ollie27
…ochenkov Suggest installing VS Build Tools in more situations When MSVC's `link.exe` wasn't found but another `link.exe` was, the error message given can be [impenetrable](https://pastebin.com/MRMCr7HM) to many users. The usual suspect is GNU's `link` tool. In this case, inform the user that they may need to install VS build tools. This only applies when Microsoft's link tool is expected.

…eklabnik FIX - Char documentation for unexperienced users This is my first PR on rust and even if I've read [CONTRIBUTING.md](https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#pull-requests) I'm ensure everything is perfect. Sorry if I didn't follow the exact procedure. **What it does:** - Add an example in the char documentation **Explanation** Unexperienced users might not know that punctuation is `Case_Ignorable` and not `Uppercase` and `Lowercase` which mean that when checking if a string is uppercase one might be tempted to write: ```rust my_string.chars().all(char::is_uppercase) ``` However this will return false for `"HELLO WORLD"` which is not intuitive. Since the function `is_case_ignorable` doesn't exists I believe the correct way to check is: ```rust !my_string.chars().any(char::is_lowercase) ``` The aim of this example is to prevent unexperienced users to make an error which punctuation chars.
llvm: Expose tiny code model to users This model is relevant to embedded AArch64 targets and was added to LLVM relatively recently (https://reviews.llvm.org/D49673, mid 2018), so rustc frontend didn't provide access to it with `-C code-model`. The gcc analogue is [`-mcmodel=tiny`](https://gcc.gnu.org/onlinedocs/gcc/AArch64-Options.html). (This is one of the options that are passed directly to LLVM without being interpreted by rustc.) Follow up to rust-lang#72248.
