Haojian Wu 8805316172 [clangd] Speed up when building rename edit.
Summary:
We used to scan the code everytime when computing the LSP position to the offset
(respect the LSP encoding). Now we only scan the source code once.

[NFC] ASSERT_EQ before accessing items in containers
As discussed offline, something different from `EXPECT_EQ` should be
used to check if the container contains enough items before accessing
them so that other tests can still be run even if the assertion fails as
opposed to having `EXPECT_EQ` failing and then aborting the run due to
the errors caused by out-of-bounds memory access.

Haojian Wu 852bafae2b [clangd] Implement cross-file rename.
Summary:
This is the initial version. The cross-file rename is purely based on
the index.

It is hidden under a command-line flag, and only available for a small set
of symbols.

[clangd] Fix diagnostic location for macro expansions
Summary:
Diagnostic locations were broken when it was result of a macro

[clangd] Improve symbol qualification in DefineInline code action
Summary:
Currently define inline action fully qualifies any names in the
function body, which is not optimal and definitely natural.

This patch tries to improve the situation by dropping any name
specifiers shared by function and names spelled in the body. For example
if you are moving definition of a function in namespace clang::clangd,
and body has any decl's coming from clang or clang::clangd namespace,
those qualifications won't be added since they are redundant.

It also drops any qualifiers that are visible in target context.

[clangd] Show lambda signature for lambda autocompletions
The original bug report can be found
[here](https://github.com/clangd/clangd/issues/85)

Given the following code:

```c++
void function() {
  auto Lambda = [](int a, double &b) {return 1.f;};
  La^
}
```

Triggering the completion at `^` would show `(lambda)` before this patch
and would show signature `(int a, double &b) const`, build a snippet etc
with this patch.

Sam McCall 765b1250f6 [clangd] Untangle Hover from XRefs, move into own file.
Summary:
This is mostly mechanical, with a few exceptions:
 - getDeducedType moved into AST.h where it belongs. It now takes
   ASTContext instead of ParsedAST, and avoids using the preprocessor.
 - hover now uses SelectionTree directly rather than via
   getDeclAtPosition helper
 - hover on 'auto' used to find the decl that contained the 'auto' and
   use that to set Kind and documentation for the hover result.
   Now we use targetDecl() to find the decl matching the deduced type instead.
   This changes tests, e.g. 'variable' -> class for auto on lambdas.
   I think this is better, but the motivation was to avoid depending on
   the internals of DeducedTypeVisitor. This functionality is removed
   from the visitor.

Sam McCall a433e7141f [AST] Attach comment in `/** doc */ typedef struct A {} B` to B as well as A.
Summary:
Semantically they're the same thing, and it's important when the underlying
struct is anonymous.

There doesn't seem to be a problem attaching the same comment to multiple things
as it already happens with `/** doc */ int a, b;`

This affects an Index test but the results look better (name present, USR points
to the typedef).

Sam McCall 713c30b389 [clangd] Don't consider class template params part of constructor name.
Summary:
This is shorter and usually the extra info is noise.
There are cases where the params become type-parameter-0-0 that are hard to fix.

This affects a few features:
 - 'name' field in structured hover API (not exposed yet)
 - 'name' field in locateSymbolAt (not exposed in LSP)
 - 'document/symbol' - the symbol is hierarchically nested in the class
   template, or written as foo<t>::foo when defined out-of-line.

Added a test case for hover from https://github.com/clangd/clangd/issues/76.
This patch fixes one field, but no fewer than four others are wrong!
I'll fix them...

Sam McCall ad9fd32009 [clangd] Fix SelectionTree behavior on constructor init-lists.
Summary:
For the constructor Foo() : classmember(arg) {}

The AST looks like:
 - CXXCtorInitializer  classmember(arg)
   - CXXConstructExpr  classmember(arg)
     - DeclRefExpr:                arg

We want the 'classmember' to be associated with the CXXCtorInitializer, not the
CXXConstructExpr. (CXXConstructExpr is known to have bad ranges).
So just early-claim it.

Thanks @hokein for tracking down/reducing the bug.

Summary:
we have a few places using `ASTCtx.getLangOpts().IsHeaderFile` to

To solve this problem, we infer the file from file name, actual changes will
come in follow-ups.

Sam McCall bbcbb10e2d [clangd] Ignore more implicit nodes in computing selection.
Summary:
The DeclRefExpr for the callee of overloaded `operator()` and `operator[]` are
assigned the range of the paren/bracket lists in the AST.
These are better thought of as implicit (at least `()` - `[] is murkier).
But there's no bit on Expr for implicit, so just ignore them on our side.

While here, deal with the case where an implicit stmt (e.g. implicit-this)
is wrapped in an implicit cast. Previously we ignored the statement but not
the cast, and so the cast ended up being selected.

Ilya Biryukov 87e0cb4f1a [clangd] Implement semantic highlightings via findExplicitReferences
Summary:
To keep the logic of finding locations of interesting AST nodes in one
place.

The advantage is better coverage of various AST nodes, both now and in
the future: as new nodes get added to `findExplicitReferences`, semantic
highlighting will automatically pick them up.

The drawback of this change is that we have to traverse declarations
inside our file twice in order to highlight dependent names, 'auto'
and 'decltype'. Hopefully, this should not affect the actual latency
too much, most time should be spent in building the AST and not
traversing it.
