Rich Kadel a7bc1a2edf Make codegen coverage_context optional, and check 
Addresses Issue #78286

Libraries compiled with coverage and linked with out enabling coverage
would fail when attempting to add the library's coverage statements to
the codegen coverage context (None).

Now, if coverage statements are encountered while compiling / linking
with `-Z instrument-coverage` disabled, codegen will *not* attempt to
add code regions to a coverage map, and it will not inject the LLVM
instrprof_increment intrinsic calls.

bors 7bade6ef73 Auto merge of #77015 - davidtwco:check-attr-variant-closure-expr, r=lcnr 
passes: `check_attr` on more targets

This PR modifies `check_attr` so that:

- Enum variants are now checked (some attributes would not have been prohibited on variants previously).
- `check_expr_attributes` and `check_stmt_attributes` are removed as `check_attributes` can perform the same checks. This means that codegen attribute errors aren't shown if there are other errors first (e.g. from other attributes, as shown in `src/test/ui/macros/issue-68060.rs` changes below).

fix validation for rustc_allow_const_fn_unstable targets 
The validation was introduced in 3a63bf0299
without strict validation of functions, e. g. all function types were
allowed.
Now the validation only allows `const fn`s.

rename allow_internal_unstable() to rustc_allow_const_fn_unstable() in rustc_mir 
Followup rename from 05f4a9a42a,
which introduced `#[rustc_allow_const_fn_unstable]` for `const fn`s.

Code cleaning made according to suggestions in discussion

 2020-10-23 11:41:19 +02:00
Canop e8df2a4269 remove option.insert_with 
`option.insert` covers both needs anyway, `insert_with` is
redundant.
 2020-10-23 11:41:19 +02:00
Canop 9b90e1762e add insert and insert_with to Option 
This removes a cause of `unwrap` and code complexity.

This allows replacing

```
option_value = Some(build());
option_value.as_mut().unwrap()
```

with

```
option_value.insert(build())
```

or

```
option_value.insert_with(build)
```

It's also useful in contexts not requiring the mutability of the reference.

Here's a typical cache example:

```
let checked_cache = cache.as_ref().filter(|e| e.is_valid());
let content = match checked_cache {
	Some(e) => &e.content,
	None => {
	    cache = Some(compute_cache_entry());
	    // unwrap is OK because we just filled the option
	    &cache.as_ref().unwrap().content
	}
};
```

It can be changed into

```
let checked_cache = cache.as_ref().filter(|e| e.is_valid());
let content = match checked_cache {
	Some(e) => &e.content,
	None => &cache.insert_with(compute_cache_entry).content,
};
```

Reduce diagram mess in 'match arms have incompatible types' error

I noticed this wild diagram in https://twitter.com/a_hoverbear/status/1318960787105353728 which I think does not benefit from the big outer vertical span.

This PR shrinks the outer span to cover just the `match` keyword and scrutinee expression *if* at least one of the highlighted match arms involved in the error is multiline.
