Summary:
This helps minimize the disruption of not returning declarations as part of
a find-definition response (r352864).

Summary:
This reduces the per-check implementation burden and redundant work.
It also makes checks range-aware by default (treating the commonAncestor
as if it were a point selection should be good baseline behavior).

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.

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.

This should not happen in normal operation, as it implies that the diagnostics
with some available fixes were produced but the AST is invalid.
Moreover, the code had an error: always returned code actions ignoring the
SupportsCodeAction capability and writing a test for this is impossible,
since this can only happen due to programmer's error rather than invalid inputs.

This looks like a useful user-facing configuration parameter,

Summary:
The code tweaks are an implementation of mini-refactorings exposed
via the LSP code actions. They run in two stages:
- Stage 1. Decides whether the action is available to the user and
collects all the information required to finish the action.
Should be cheap, since this will run over all the actions known to
clangd on each textDocument/codeAction request from the client.
- Stage 2. Uses information from stage 1 to produce the actual edits
that the code action should perform. This stage can be expensive and
will only run if the user chooses to perform the specified action in
the UI.
One unfortunate consequence of this change is increased latency of
processing the textDocument/codeAction requests, which now wait for an
AST. However, we cannot avoid this with what we have available in the LSP
today.

Summary:
This enables clangd to intercept compiler diagnostics and attach fixes (e.g. by
querying index). This patch adds missing includes for incomplete types e.g.
member access into class with only forward declaration. This would allow adding
missing includes for user-typed symbol names that are missing declarations
(e.g. typos) in the future.

With ObjCPropertyDecl, ASTNode.OrigD can be a ObjCPropertyImplDecl
which is not a NamedDecl, leading to a crash since the code
incorrectly assumes ASTNode.OrigD will always be a NamedDecl.

ClangTidyOptions::getDefaults is not free, it will initialize all
clang-tidy modules to get check-specific options, and we don't use this
information in CodeComplete, so using an empty one (constructed by
default constructor) is sufficient.
llvm-svn: 351826
Summary:
This patch adds some basic supports for clang-tidy configurations in clangd:
- clangd will respect .clang-tidy configurations for each file
- we don't aim to support all clang-tidy options in clangd, only a
small subset of condfigurations (options related to which checks will be
enabled) are supported.
- add a `clang-tidy-checks` CLI option that can override options from
.clang-tidy file

Some projects make use of clang plugins when building, but clangd is
not aware of those plugins therefore can't work with the same compile command
arguments.
There were multiple places clangd performed commandline manipulations,
this one also moves them all into OverlayCDB.

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.
