Haojian Wu c8f7496257 [clangd] Don't attach FixIt to the source code in macro.
Summary:
We are less certain it is the correct fix. Also, clang doesn't apply FixIt to
the source code in macro.

Kadir Cetinkaya 748211a81f [clangd] Only report explicitly typed symbols during code navigation
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);`

Jonas Toth 32d5b252b9 [clang-tidy] refactor ExceptionAnalyzer further to give ternary answer
Summary:
The analsis on the throwing behvaiour on functions and statements gave only
a binary answer whether an exception could occur and if yes which types are
thrown.
This refactoring allows keeping track if there is a unknown factor, because the
code calls to some functions with unavailable source code with no `noexcept`
information.
This 'potential Unknown' information is propagated properly and can be queried
separately.

Eric Liu 4df070a5e3 [clangd] Handle unresolved scope specifier when fixing includes.
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).

BuiltinType.
An enum cannot be initialized by assigning 0 to it unless a cast is added.
It could be initialized with an enumerator with the value 0, but there might not
be one.
Avoid these issues by ignoring the UseAssignment setting for value-initialized
enums.

Fixes PR35050.

Sam McCall 2048f22892 [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.

I intent to use that class in a new check to automatically introduce `noexcept`

Ilya Biryukov cce67a32cf [clangd] Interfaces for writing code tweaks
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 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

arguments.

There were multiple places clangd performed commandline manipulations,
 this one also moves them all into OverlayCDB.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Chandler Carruth 469bdefd44 Install new LLVM license structure and new developer policy.
This installs the new developer policy and moves all of the license
files across all LLVM projects in the monorepo to the new license
structure. The remaining projects will be moved independently.

Note that I've left odd formatting and other idiosyncracies of the
legacy license structure text alone to make the diff easier to read.
Critically, note that we do not in any case *remove* the old license
notice or terms, as that remains necessary until we finish the
relicensing process.

I've updated a few license files that refer to the LLVM license to
instead simply refer generically to whatever license the LLVM project is
under, basically trying to minimize confusion.

This is really the culmination of so many people. Chris led the
community discussions, drafted the policy update and organized the
multi-year string of meeting between lawyers across the community to
figure out the strategy. Numerous lawyers at companies in the community
spent their time figuring out initial answers, and then the Foundation's
lawyer Heather Meeker has done *so* much to help refine and get us ready
here. I could keep going on, but I just want to make sure everyone
realizes what a huge community effort this has been from the begining.
