Tweak `self` arg not as first argument of a method diagnostic
Mention that `self` is only valid on "associated functions"
```
error: unexpected `self` argument in function
--> $DIR/self-in-function-arg.rs:1:15
|
LL | fn foo(x:i32, self: i32) -> i32 { self }
| ^^^^ not valid as function argument
|
= note: `self` is only valid as the first argument of an associated function
```
When it is a method, mention it must be first
```
error: unexpected `self` argument in function
--> $DIR/trait-fn.rs:4:20

LL | fn c(foo: u32, self) {}

Move a bunch of error recovery methods to `diagnostics.rs` away from `parser.rs`.

Move async/await tests to their own folder
This moves run-pass and ui async/await tests to their own folder `src/test/ui/async-await` and organises some into subfolders. (It does not move rustdoc tests for async/await.)
I also did some drive-by cleaning up of issues/error code tests into their own folders (which already existed). These are in separate commits, so easy to separate out if that's more desirable.

- Add detail on origin of current parser when reaching EOF and stop
saying "found <eof>" and point at the end of macro calls
- Handle empty `cfg_attr` attribute
- Reword empty `derive` attribute error
Remove `ObsoleteInPlace`
The in place syntax has been deprecated for over a year. As it is, this is accumulated cruft: the error messages are unlikely to be helpful any more and it conflicts with some useful syntax (e.g. const generics in some instances).
It may be that removing `Token::LArrow` is backwards-incompatible. We should do a crater run to check.

Borrowck error reporting cleanup
* Don't show variables created by desugarings in borrowck errors
* Move "conflict error" reporting to it's own module, so that `error_reporting` contains only common error reporting methods.
* Remove unused `ScopeTree` parameter.
