Rollup merge of #77758 - Stupremee:turbofish-help-for-const, r=varkor 
suggest turbofish syntax for uninferred const arguments

When not providing a const generic value, and it can not be inferred, the following suggestion is suggested:

Rollup merge of #78463 - varkor:placeholder-const, r=nikomatsakis 
Add type to `ConstKind::Placeholder`

I simply threaded `<'tcx>` through everything that required it. I'm not sure whether this is the correct thing to do, but it seems to work.

Rollup merge of #76765 - guswynn:async_return, r=tmandry 
Make it more clear what an about async fn's returns when referring to what it returns

see #76547

This is *likely* not the ONLY place that this happens to be unclear, but we can move this fn to rustc_middle or something like that and reuse it if need be, to apply it to more diagnostics

One outstanding question I have is, if the fn returns (), should I make the message more clear (what about `fn f()` vs `fn f() -> ()`, can you tell those apart in the hir?)

Rollup merge of #78460 - varkor:turbofish-string-generic, r=lcnr 
Adjust turbofish help message for const generics

Types are no longer special. (This message arguably only makes sense with `min_const_generics` or more, but we'll be there soon.)

28f02fbf3e Suggest calling await on method call and field access 
When encountering a failing method or field resolution on a `Future`,
look at the `Output` and try the same operation on it. If successful,
suggest calling `.await` on the `Future`.

This had already been introduced in #72784, but at some point they
stopped working.

5c224a484d MiniSet/MiniMap moved and renamed into SsoHashSet/SsoHashMap 
It is a more descriptive name and with upcoming changes
there will be nothing "mini" about them.
