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

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.
