This is useful for running in batch mode.
Getting the SymbolID from via getSymbolInfo may give SymbolID
of a symbol different from that located by LocateSymbolAt (they
have different semantics of choosing the symbol.)

```
struct A { virtual void foo() = 0; };
struct B : A { void foo() override; };
```
Find refs on `A::foo()` will show:
- decls of `A::foo()`
- decls of `B::foo()`
- refs to `A::foo()`
- no refs to `B::foo()`.

Unfortunately this treats overrides declarations as declarations, not as
references. I don't plan to land this until I have a fix for that issue.

Summary:
This is intended as a companion to (and is inspired by) D72874 which attempts to
resolve these cases using the index.
The intent is we'd try this strategy after the AST-based approach but before the
index-based (I think local usages would be more reliable than index matches).

This facilitates performing go-to-definition in contexts where AST-based
resolution does not work, such as comments, string literals, preprocessor

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.
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.
Summary:
This adds an implementation for the "textDocument/documentLink" LSP request.
It returns links for all `#include` directives to the resolved target files.
Fixes https://github.com/clangd/clangd/issues/217.

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.

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

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.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

llvm-svn: 347675
Summary:
This patch adds index support for GoToDefinition -- when we don't get the
definition from local AST, we query our index (Static&Dynamic) index to
get it.
Since we currently collect top-level symbol in the index, it doesn't support all
cases (e.g. class members), we will extend the index to include more symbols in
the future.

Summary: Implemention of textDocument/hover as described in LSP definition.
This patch adds a basic Hover implementation. When hovering a variable,
function, method or namespace, clangd will return a text containing the
declaration's scope, as well as the declaration of the hovered entity.
For example, for a variable:
Declared in class Foo::Bar
int hello = 2
For macros, the macro definition is returned.
This patch doesn't include:
- markdown support (the client I use doesn't support it yet)
- range support (optional in the Hover response)
- comments associated to variables/functions/classes
They are kept as future work to keep this patch simpler.
I added tests in XRefsTests.cpp. hover.test contains one simple
smoketest to make sure the feature works from a black box perspective.

llvm-svn: 325395
Summary:
Instead of passing Context explicitly around, we now have a thread-local
Context object `Context::current()` which is an implicit argument to
every function.
Most manipulation of this should use the WithContextValue helper, which
augments the current Context to add a single KV pair, and restores the
old context on destruction.
Advantages are:
- less boilerplate in functions that just propagate contexts
- reading most code doesn't require understanding context at all, and
using context as values in fewer places still
- fewer options to pass the "wrong" context when it changes within a
scope (e.g. when using Span)
- contexts pass through interfaces we can't modify, such as VFS
- propagating contexts across threads was slightly tricky (e.g.
copy vs move, no move-init in lambdas), and is now encapsulated in
the threadpool
Disadvantages are all the usual TLS stuff - hidden magic, and
potential for higher memory usage on threads that don't use the
context. (In practice, it's just one pointer)
