1213: Make lexer produce only single character puncts r=matklad a=edwin0cheng
As discussed in Zulip, this PR change `lexer` to produce only single char punct.
* Remove producing `DOTDOTDOT, DOTDOTEQ, DOTDOT, COLONCOLON, EQEQ, FAT_ARROW, NEQ, THIN_ARROW` in lexer.
* Add required code in parser to make sure everythings works fine.
* Change some tests (Mainly because the `ast::token_tree` is different)
Note: i think the use of `COLON` in rust is too overloaded :)

E.g. in
```
let foo = 1u32;
if true {
<|>foo;
}
```
the hover shows `()`, the type of the whole if expression, instead of the more
sensible `u32`. The reason for this was that the search for an expression was
slightly left-biased: When on the edge between two tokens, it first looked at
all ancestors of the left token and then of the right token. Instead merge the
ancestors in ascending order, so that we get the smaller of the two possible
expressions.

1200: Allows searching for case-equivalent symbols (fixes #1151) r=matklad a=jrvidal
I couldn't find a nice, functional way of calculating the ranges in one pass so I resorted to a plain old `for` loop.

1147: Handle macros in type checking / HIR r=matklad a=Lapz
An other attempt at #1102. I will need to flatten the nested if statements and im also not sure if the way that i get the resolver and module will always work

1194: Pr 1190 r=matklad a=matklad

We really shouldn't be looking at the identifier at point. Instead,
all filtering and sorting should be implemented at the layer above.
This layer should probably be home for auto-import completions as
well, but, since that is not yet implemented, let's just stick this
into complete_scope.

auto-import is purely an IDE concern, so it should be done outside of
HIR

1184: Start structured editing API r=matklad a=matklad
I think I finally understand how to provide nice, mutable structured editing API on top of red-green trees.
The problem I am trying to solve is that any modification to a particular `SyntaxNode` returns an independent new file. So, if you are editing a struct literal, and add a field, you get back a SourceFile, and you have to find the struct literal inside it yourself! This happens because our trees are immutable, but have parent pointers.
The main idea here is to introduce `AstEditor<T>` type, which abstracts away that API. So, you create an `AstEditor` for node you want to edit and call various `&mut` taking methods on it. Internally, `AstEditor` stores both the original node and the current node. All edits are applied to the current node, which is replaced by the corresponding node in the new file. In the end, `AstEditor` computes a text edit between old and new nodes.
Note that this also should sole a problem when you create an anchor pointing to a subnode and mutate the parent node, invalidating anchor. Because mutation needs `&mut`, all anchors must be killed before modification.

Currently, this is more code, and we also loose auto-indenting of
bodies, but, long-term, this is the right approach
