Ilya Biryukov 373bee85c2 [clangd] Tune the fuzzy-matching algorithm
Summary:
To reduce the gap between prefix and initialism matches.

The motivation is producing better scoring in one particular example,
but the change does not seem to cause large regressions in other cases.

The examples is matching 'up' against 'unique_ptr' and 'upper_bound'.
Before the change, we had:
  - "[u]nique_[p]tr" with a score of 0.3,
  - "[up]per_bound" with a score of 1.0.

A 3x difference meant that symbol quality signals were almost always ignored
and 'upper_bound' was always ranked higher.

However, intuitively, the match scores should be very close for the two.

After the change we have the following scores:
- "[u]nique_[p]tr" with a score of 0.75,
- "[up]per_bound" with a score of 1.0.

Kadir Cetinkaya d9c174648e [clangd] Store explicit template specializations in index for code navigation purposes
Summary:
This introduces ~4k new symbols, and ~10k refs for LLVM. We need that
information for providing better code navigation support:
- When references for a class template is requested, we should return these specializations as well.
- When children of a specialization is requested, we should be able to query for those symbols(instead of just class template)

Number of symbols: 378574 -> 382784
Number of refs: 5098857 -> 5110689

Kadir Cetinkaya 65944ab50d [clangd] Adjust compile commands to be applicable for tooling
Summary:
As can be seen in https://github.com/llvm-mirror/clang/blob/master/lib/Tooling/Tooling.cpp#L385
clang tool invocations adjust commands normally like this. In clangd we have
different code paths for invoking a frontend action(preamble builds, ast builds,
background index, clangd-indexer) they all work on the same GlobalCompilationDatabase
abstraction, but later on are subject to different modifications.

This patch makes sure all of the clangd actions make use of the same compile
commands before invocation.

Enables background-index to work on chromium codebase(since they had dependency
file output in their compile commands).

Summary:

Summary:
Clangd was reporting implicit symbols, like results of implicit cast
expressions during code navigation, which is not desired. For example:

```
struct Foo{ Foo(int); };
void bar(Foo);
vod foo() {
  int x;
  bar(^x);
}
```
Performing a GoTo on the point specified by ^ would give two results one
pointing to line `int x` and the other for definition of `Foo(int);`

Summary:
In the following examples, "clangd" is unresolved, and the fixer will try to fix
include for `clang::clangd`; however, clang::clangd::X is usually intended. So
when handling a qualifier that is unresolved, we change the unresolved name and
scopes so that the fixer will fix "clang::clangd::X" in the following example.
```
  namespace clang {
  	clangd::X
	~~~~~~
  }
  // or
  clang::clangd::X
         ~~~~~~
```

Summary:
Multiple diagnostics can be caused by the same unresolved name or incomplete type,
especially if the code is copy-pasted without #includes. The cache can avoid making
repetitive index requests, and thus reduce latency and allow more diagnostics to be
fixed (we limit the number of index requests for each parse).

Sam McCall 3186e3ceb8 [clangd] Lib to compute and represent selection under cursor.
Summary:
The primary problem this solves is to expose the codeAction selection to
AST-based refactorings in a way that makes it easy and efficient for them to
bind to the right parts of the AST.

It should also allow us to make XRefs based features (textDocument/definition)
more robust, more easily implement textDocument/typeDefinition etc.
As an example, template parameter references can be identified without special
handling.
There should be slight speedup too: we can prune most of the AST traversal
in most cases.

Elephant in the room: this is similar-but-different to Tooling/Refactoring/ASTSelection.
That captures a smaller set of AST nodes, has a slightly different way of
representing selections, and generally has mare features and does more work.
The overall shape is pretty similar, and yet I can't quite get to behave as I
expect.

Sam McCall 866ba2c924 [clangd] Implement textDocument/declaration from LSP 3.14
Summary:
LSP now reflects the declaration/definition distinction.

Language server changes:
 - textDocument/definition now returns a definition if one is found, otherwise
   the declaration. It no longer returns declaration + definition if they are
   distinct.
 - textDocument/declaration returns the best declaration we can find.
 - For macros, the active macro definition is returned for both methods.
 - For include directive, the top of the target file is returned for both.
There doesn't appear to be a discovery mechanism (we can't return everything to
clients that only know about definition), so this changes existing behavior.
In practice, it should greatly reduce the fraction of the time we need to show
the user a menu of options.

C++ API changes:
 - findDefinitions is replaced by locateSymbolAt, which returns a
   vector<LocatedSymbol> - one for each symbol under the cursor.
 - this contains the preferred declaration, the definition (if found), and
   the symbol name
This API enables some potentially-neat extensions, like swapping between decl
and def, and exposing the symbol name to the UI in the case of multiple symbols.
