It is not great to list diag ids by hand, but I don't see any other
solution unless diagnostics are annotated with these explicitly, which is a
bigger change in clang and I am not sure if would be worth it.
Diagnostics handled by this patch is by no means exhaustive, there might be
other checks that don't mention "unused"/"deprecated" in their names. But it
feels like this should be enough to catch common diagnostics and can be extended
over time.

Ignored diagnostics were only checked after level adjusters and assumed
it would stay the same for the rest. But it can also be modified by
FeatureModules.
Differential Revision: https://reviews.llvm.org/D103387
These can be invoked at different stages while building an AST to let
FeatureModules implement features on top of it. The patch also
introduces a sawDiagnostic hook, which can mutate the final clangd::Diag
while reading a clang::Diagnostic.

We don't act as a language server for these files (e.g. don't get open/close
notifications for them), but just blindly publish diagnostics for them.
This works reasonably well in coc.nvim and vscode: they show up in the
workspace diagnostic list and when you open the file.
The only update after the file is reparsed, not as you type which is a bit
janky, but seems a lot better than nothing.

This can happen when building implicit modules, as demonstrated in test.
The CompilerInstance uses the same StoredDiags, but different
SourceManager. This used to crash clangd when it tried to relocate the
diagnostic to the main file, which, according to SourceManager from the
diagnostic, is a fake <module-includes> file.

I think this is uncovering a latent bug when a late-parsed preamble is
used with an eagerly-parsed file.
Summary:
Parsing std::make_unique is an exception to the usual non-parsing of function
bodies in the preamble. (A hook is added to PreambleCallbacks to allow this).
This allows us to diagnose make_unique<Foo>(wrong arg list), and opens the door
to providing signature help (by detecting where the arg list is forwarded to).
This function is trivial (checked libc++ and libstdc++) and doesn't result in
any extra templates being instantiated, so this should be cheap.
This uncovered a second issue (already visible with class templates)...
Errors produced by template instantiation have primary locations within the
template, with instantiation stack reported as notes.
For templates defined in headers, these end up reported at the #include
directive, which isn't terribly helpful as the header itself is probably fine.
This patch reports them at the instantiation site (the first location in the
instantiation stack that's in the main file). This in turn required a bit of
refactoring in Diagnostics so we can delay relocating the diagnostic until all
notes are available.

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.

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.

Summary:
CodeAction provides us with a standard way of representing fixes inline, so
use it, replacing our existing ad-hoc extension.
After this, it's easy to serialize diagnostics using the structured
toJSON/Protocol.h mechanism rather than assembling JSON ad-hoc.

client if the client supports this extension
This commit extends the 'textDocument/publishDiagnostics' notification sent from
Clangd to the client. When it's enabled, Clangd sends out the fixits associated
with the appropriate diagnostic in the body of the 'publishDiagnostics'
notification. The client can enable this extension by setting 'clangdFixSupport'
to true in the textDocument capabilities during initialization.
