Sam McCall 489cc589c5 [clangd] Add targetDecl(), which determines what declaration an AST node refers to.
Summary:
This is the first part of an effort to "unbundle" our libIndex use into separate
concerns (AST traversal, token<->node mapping, node<->decl mapping,
decl<->decl relationshipes).

Currently, clangd relies on libIndex to associate tokens, AST nodes, and decls.
This leads to rather convoluted implementations of e.g. hover and
extract-function, which are not naturally thought of as indexing applications.

The idea is that by decoupling different concerns, we make them easier
to use, test, and combine, and more efficient when only one part is needed.
There are some synergies between e.g. traversal and finding
relationships between decls, hopefully the benefits outweight these.

Sam McCall 9470142ca5 [clangd] Implementation of auto type expansion.
Add a tweak for clangd to replace an auto keyword to the deduced type.

This way a user can declare something with auto and then have the
IDE/clangd replace auto with whatever type clangd thinks it is. In case
of long/complext types this makes is reduces writing effort for the
user.

The functionality is similar to the hover over the auto keyword.

Example (from the header):

```
/// Before:
///    auto x = Something();
///    ^^^^
/// After:
///    MyClass x = Something();
///    ^^^^^^^
```
