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

1195: Add cached for SubtreeSource r=matklad a=edwin0cheng
I just did some simple profiling, the most slowest part of the mbe related code is the tree traversal, so i add a very simple cache in here is the result:

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.

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.

1192: Add mbe expand limit and poision macro set r=maklad a=edwin0cheng
As discussed in Zulip, this PR add a token expansion limit in `parse_macro` and a "poison" macro set in `CrateDefMap` to prevent stack over flow and limit a mbe macro size.
Note:
Right now it only handle a poison macro in a single crate, such that if other crate try to call that macro, the whole process will do again until it became poisoned in that crate.

1189: Fix#1178 r=matklad a=edwin0cheng
This PR improves / fixes mbe :
1. Fixed a offest bug in `SourceTreeWalker`
2. Handle `*+` matcher properly
3. Add missing separator in rhs macro expansion.
4. Fixed bug in single token with empty delimiter subtree case. It is because the current `mbe_expander` will create an delimiter subtree for each expansion. But in `tt` case, all puncts expansion will be incorrect because of it.
5. Fixed lifetime bug
6. Add more information on parse_macro fail
7. Add tests for above.

1182: Add HIR for where clauses & ignore impls with where clauses in trait resolution r=matklad a=flodiebold
This prevents any `impl<T> Trait for T where ...` from being treated as a
blanket impl while we don't handle where clauses yet.
