Rename `type_parameters` to `generics` and so on
Some old variable names had fallen through the generics generalisation pull requests.

Type dependent defs wrappers
First of all, forgive me if something would seem lame to you or I offend some rule (although I tried to read through docs), this is my first PR.
Issue: https://github.com/rust-lang/rust/issues/59094
This PR adds 3 helper methods to `TypeckTables`:
* `opt_type_dependent_def`
* `opt_type_dependent_def_id`
* `type_dependent_def_id`
I didn't add `type_dependent_def` as was proposed in the issue simply because it wasn't used anywhere in the code. Only non-option wrapped`type_dependent_defs()[]` accesses were found in clippy which always called `def_id()` on result.
Speaking of clippy, should I open separate PR in its own repo, given it's used as submodule here?
Sry it took me so long, as I said I'm new here and I had tough week :).

This commit moves the `DefId` field of `Def::Ctor` to be the first
field.
|
|
This commit moves the definition of `CtorOf` from `rustc::hir` to
`rustc::hir::def` and adds imports wherever it is used.
|

This commit makes two changes - separating the `NodeId` that identifies
an enum variant from the `NodeId` that identifies the variant's
constructor; and no longer creating a `NodeId` for `Struct`-style enum
variants and structs.
Separation of the variant id and variant constructor id will allow the
rest of RFC 2008 to be implemented by lowering the visibility of the
variant's constructor without lowering the visbility of the variant
itself.
No longer creating a `NodeId` for `Struct`-style enum variants and
structs mostly simplifies logic as previously this `NodeId` wasn't used.
There were various cases where the `NodeId` wouldn't be used unless
there was an unit or tuple struct or enum variant but not all uses of
this `NodeId` had that condition, by removing this `NodeId`, this must
be explicitly dealt with. This change mostly applied cleanly, but there
were one or two cases in name resolution and one case in type check
where the existing logic required a id for `Struct`-style enum variants
and structs.

middle: replace NodeId with HirId in AccessLevels
Pushing the limits of HirIdification (#57578).
Replaces `NodeId` with `HirId` in `middle::privacy::AccessLevels`. Actually this time I was more successful and cracked it; I probably tried to HirIdify too much at once when I attempted it last time ^^.

When failing to parse struct-like enum variants, the ADT gets recorded
as having no fields. Record that we have actually recovered during
parsing of this variant to avoid complaing about non-existing fields
when actually using it.

Support defining C compatible variadic functions
## Summary
Add support for defining C compatible variadic functions in unsafe rust with
`extern "C"` according to [RFC 2137].
## Details
### Parsing
When parsing a user defined function that is `unsafe` and `extern "C"` allow
variadic signatures and inject a "spoofed" `VaList` in the new functions
signature. This allows the user to interact with the variadic arguments via a
`VaList` instead of manually using `va_start` and `va_end` (See [RFC 2137] for
details).
### Codegen
When running codegen for a variadic function, remove the "spoofed" `VaList`
from the function signature and inject `va_start` when the arg local
references are created for the function and `va_end` on return.
## TODO
- [x] Get feedback on injecting `va_start/va_end` in MIR vs codegen
- [x] Properly inject `va_end` - It seems like it should be possible to inject
`va_end` on the `TerminatorKind::Return`. I just need to figure out how
to get the `LocalRef` here.
- [x] Properly call Rust defined C variadic functions in Rust - The spoofed
`VaList` causes problems here.

Deny `async fn` in 2015 edition
This commit prevents code using `async fn` from being compiled in Rust 2015 edition.
Compiling code of the form:
```rust
async fn foo() {}
```
Will now result in the error:
```
error[E0670]: `async fn` is not permitted in the 2015 edition
--> async.rs:1:1
|
1 | async fn foo() {}
| ^^^^^
error: aborting due to error
For more information about an error, try `rustc --explain E0670`.
```
This resolves #58652 and also resolves #53714.

From 104 bytes to 72 bytes on x86-64. This slightly reduces instruction
counts.
Also add an assertion about the size.

Cleanup: rename node_id_to_type(_opt)
Renames `node_id_to_type(_opt)` to `hir_id_to_type(_opt)`; this makes it clear we are dealing with HIR nodes and their IDs here.
In addition, a drive-by commit removing `ty::item_path::hir_path_str` (as requested by @eddyb).

Cosmetic improvements to doc comments
This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase).
r? @steveklabnik
Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

Always calculate glob map but only for glob uses
Previously calculating glob map was *opt-in*, however it did record node id -> ident use for every use directive. This aims to see if we can unconditionally calculate the glob map and not regress performance.
Main motivation is to get rid of some of the moving pieces and simplify the compilation interface - this would allow us to entirely remove `CrateAnalysis`. Later, we could easily expose a relevant query, similar to the likes of `maybe_unused_trait_import` (so using precomputed data from the resolver, but which could be rewritten to be on-demand).
r? @nikomatsakis
Local perf run showed mostly noise (except `ctfe-stress-*`) but I'd appreciate if we could do a perf run run here and double-check that this won't regress performance.

save-analysis: Get path def from parent in case there's no def for the path itself.
This fixes #57462.
The relevant part from the hir type collector is:
```
DEBUG 2019-01-09T15:42:58Z: rustc::hir::map::collector: hir_map: NodeId(32) => Entry { parent: NodeId(33), dep_node: 4294967040, node: Expr(expr(32: <Foo>::new)) }
DEBUG 2019-01-09T15:42:58Z: rustc::hir::map::collector: hir_map: NodeId(48) => Entry { parent: NodeId(32), dep_node: 4294967040, node: Ty(type(Foo)) }
DEBUG 2019-01-09T15:42:58Z: rustc::hir::map::collector: hir_map: NodeId(30) => Entry { parent: NodeId(48), dep_node: 4294967040, node: PathSegment(PathSegment { ident: Foo#0, id: Some(NodeId(30)), def: Some(Err), args: None, infer_types: true }) }
DEBUG 2019-01-09T15:42:58Z: rustc::hir::map::collector: hir_map: NodeId(31) => Entry { parent: NodeId(32), dep_node: 4294967040, node: PathSegment(PathSegment { ident: new#0, id: Some(NodeId(31)), def: Some(Err), args: None, infer_types: true }) }
```
We have the right ID when looking for NodeId(31) and try with NodeId(32) (which
is the right thing to look for) from get_path_data. But not when we look from `write_sub_paths_truncated`
Basically process_path takes an id which is always the parent, and that we
fall back to in get_path_data(), so we get the right result for the last path
segment, but not for the other segments that get written to from
write_sub_paths_truncated.
I think we can stop passing the explicit `id` around to get_path_data as a followup.
