Sam McCall 8d7ecc1629 Revert "Revert "[clangd] Implement "textDocument/documentLink" protocol support""
This reverts commit 079ef783dd.

The revert describes a test failure without details, after offline
discussion this in in a private/unsupported build system and doesn't
seem to reflect a real upstream bug.

Dmitri Gribenko 079ef783dd Revert "[clangd] Implement "textDocument/documentLink" protocol support"
This reverts commit d6417f5584. The tests
depend on builtin headers, which is not intentionally supported in
clangd tests; these tests are broken in some build environments.

Haojian Wu decdbc1155 [clangd] Use expansion location when the ref is inside macros.
Summary:
Previously, xrefs has inconsistent behavior when the reference is inside
macro body:
- AST-based xrefs (for main file) uses the expansion location;
- our index uses the spelling location;

This patch makes our index use file locations for references, which is
consistent with AST-based xrefs, and kythe as well.

After this patch, memory usage of static index on LLVM increases ~5%.

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...

Nico Weber 51fa7409e7 Make most clangd unittests pass on Windows
The Windows triple currently turns on delayed template parsing, which
confuses several unit tests that use templates.

For now, just explicitly disable delayed template parsing. This isn't
ideal, but:

- the Windows triple will soon no longer use delayed template parsing
  by default

- there's precedent for this in the clangd unit tests already

- let's get the clangd tests pass on Windows first before making
  behavioral changes

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();
///    ^^^^^^^
```

Sam McCall b804eef090 [clangd] Move clangd tests to clangd directory. check-clangd is no longer part of check-clang-tools.
Summary:
Motivation:
 - this layout is a pain to work with
 - without a common root, it's painful to express things like "disable clangd" (D61122)
 - CMake/lit configs are a maintenance hazard, and the more the one-off hacks
   for various tools are entangled, the more we see apathy and non-ownership.

This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.

(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).

Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.
