8557cb47cb don't store method_fty 
It is redundant with the item type. This is not much of a win,
as there are really not *that* many methods, but it makes the code
uglier.

e82faeb655 Auto merge of #28742 - nikomatsakis:def-id-encapsulate, r=eddyb 
As described in https://github.com/rust-lang/rfcs/pull/1298, the idea here is to make DefIds independent of changes to the content of other items. They are also *mostly* independent from ordering, so e.g. reordering two functions will change the defids, but it will not change the paths that they expand into (but this is not the case for some things, such as impls).

This is a major refactoring, so I did it in slices. The final commit is in some sense The Big One where most of the work is done. The earlier commits just pave the way by gradually refactoring accesses to the `node` field.

This is a [breaking-change] for plugin authors. The things you need to do to migrate your code are as follows:

1. For local def-ids, rather than do `def_id.node`, call `tcx.map.as_local_node_id(def_id)`.
2. To construct a local def-id, call `tcx.map.local_def_id(node_id)`.
3. Note that you cannot make def-ids for any node, but only for "definitions" -- which include all items, as well as a number of other things, but not e.g. arbitrary expressions.
4. You can get the path to a def-id by calling `tcx.def_path(def_id)`.

One thing that is NOT part of this PR, but which I plan do in a follow-up, is converting uses of the existing `with_path` API to use `def_path`, which is basically the same.

3b1399df2d Make calling def_id on a DefSelfTy an error; the previous defids that 
were returned, either the trait or the *self type itself*, were not
particularly representative of what the Def is (a type parameter).
Rewrite paths to handle this case specially, just as they handle the
primitive case specifically. This entire `def_id` codepath is kind of a
mess.

78edd4f3a0 Auto merge of #28778 - arielb1:no-source, r=eddyb 
this simplifies the code while reducing the size of libcore.rlib by
3.3 MiB (~1M of which is bloat a separate patch of mine removes
too), while reducing rustc memory usage on small crates by 18MiB.

This also simplifies the code considerably.

I have measured a small, but possibly insignificant, bootstrap performance improvement, and the memory savings grow to about 30M for larger crates (but that is still less as a percentage).

This commit swaps the order of linking local native libraries and upstream
native libraries on the linker command line. Detail of bugs this can cause can
be found in #28595, and this change also invalidates the test case that was
added for #12446 which is now considered a bug because the downstream dependency
would need to declare that it depends on the native library somehow.

Closes #28595

b6449eba51 Rollup merge of #28753 - steveklabnik:gh28572, r=alexcrichton 
This is part of #28572, but doesn't complete it. Amongst other things,
this patch:

* Increases consistency in the way feature flags are used with other
  docs.
* Removes the ignores, which is nice: we actually had some syntax errors
  in the examples 😭.
* Mentions #![no_core]

Realistically, this document used to be in the order of least to most:
nothing, then adding core. But with the changes in RFC 1184, this is
backwards: it now shows stuff that uses core from the beginning. In the
future, I'd like to revamp this to go from 'most to least', but I'd like
to see the discussion in https://github.com/rust-lang/rust/issues/27701
goes before I write more.
