3532863a96 Change how Symbol::Debug works. 
Currently, `Symbol::Debug` and `Symbol::Display` produce the same
output; neither wraps the symbol in double quotes.

This commit changes `Symbol::Debug` so it wraps the symbol in quotes.
This change brings `Symbol`'s behaviour in line with `String` and
`InternedString`. The change requires a couple of trivial test output
adjustments.

d8fca9ee4e Use with in Symbol trait methods. 
Instead of `as_str()`, which unnecessarily involves `LocalInternedString`.

e4ec4a6da3 Change MetaItem::tokens() to MetaItem::token_trees_and_joints(). 
Likewise for `NestedMetaItem::tokens()`. Also, add
`MetaItemKind::token_trees_and_joints()`, which `MetaItemKind::tokens()`
now calls.

This avoids some unnecessary `TokenTree` to `TokenStream` conversions,
and removes the need for the clumsy
`TokenStream::append_to_tree_and_joint_vec()`.

212ae58f36 Change Lit::tokens() to Lit::token_tree(). 
Because most of the call sites have an easier time working with a
`TokenTree` instead of a `TokenStream`.

a6eef299d3 Make TokenStream::from_iter less general and more efficient. 
The current code has this impl:
```
impl<T: Into<TokenStream>> iter::FromIterator<T> for TokenStream
```
If given an `IntoIterator<Item = TokenTree>`, it will convert each individual
`TokenTree` to a `TokenStream` (at the cost of two allocations: a `Vec`
and an `Lrc`). It will then merge those `TokenStream`s into a single
`TokenStream`. This is inefficient.

This commit changes the impl to this less general one:
```
impl iter::FromIterator<TokenTree> for TokenStream
```
It collects the `TokenTree`s into a single `Vec` first and then converts that
to a `TokenStream` by wrapping it in a single `Lrc`. The previous generality
was unnecessary; no other code needs changing.

This change speeds up several benchmarks by up to 4%.

6be0a7081a Update API to be more compatible with plugin needs 
Move to using Box<dyn Fn() -> ...> so that we can let plugins register
state.

This also adds a callback that'll get called from plugin registration so
that Clippy and other tools can register lints without using the plugin
API. The plugin API still works, but this new API is more compatible
with drivers other than rustc.

da56d1d201 Remove all borrows of lint store from Session from librustc 
Access through tcx is fine -- by that point, the lint store is frozen,
but direct access through Session will go away in future commits, as
lint store is still mutable in early stages of Session, and will be
removed completely.

aa4ee2cc0f Move to storing constructor functions inside LintStore 
This stops storing the pass objects and instead stores constructor
