This check ensures that users of Abseil do not open namespace absl in their code, as that violates our compatibility guidelines.

After r339738 Clangd started sending categories with each diagnostic, but that
broke the eglot client. This commit puts the categories behind a capability to

This check is an abseil specific check that checks for code using single character string literals as delimiters and transforms the code into characters.
The check was developed internally and has been running at google, this is just
a move to open source the check. It was originally written by @sbenza.

Summary:
Currently, there is two configured prefixes: `CHECK-FIXES` and `CHECK-MESSAGES`
`CHECK-MESSAGES` checks that there are no test output lines with `warning:|error:`, which are not explicitly handled in lit tests.
However there does not seem to be a nice way to enforce for all the `note:` to be checked.
This was useful for me when developing D36836.

performance-for-range-copy check.
Summary:
The upstream change r336737 make the check too smart to fix the case
where loop variable could be used as `const auto&`.
But for the case below, changing to `const auto _` will introduce
an unused complier warning.
```
for (auto _ : state) {
// no references for _.
}
```
This patch omit this case, and it is safe to do it as the case is very rare.

Relanding with a minor change to prevent an assertion on release bots.
The result of this adjusted mapper pass is that all Function and Enum
infos are absorbed into the info of their enclosing scope (i.e. the class
or namespace in which they are defined). Namespace and Record infos are
passed along to the final output, but the second pass creates a reference
to each in its parent scope. As a result, the top-level final outputs are
Namespaces and Records.

compilationDatabaseChanges in the 'workspace/didChangeConfiguration' request
This commit allows clangd to use an in-memory compilation database that's
controlled from the LSP client (-compile_args_from=lsp). It extends the
'workspace/didChangeConfiguration' request to allow the client to pass in a
compilation database subset that needs to be updated in the workspace.

Hello, i would like to suggest a fix for one of the checks in clang-tidy.

```
struct UOB{
UOB(const UOB &Other):j{Other.j}{}
int j;
};
```
In this case the check modernize-use-equals-default does not detect copy constructors that can be defaulted; that should be:
```
struct UOB{
UOB(const UOB &Other) = default;
int j;
};

Summary:
The goal is to reduce false positives when the difference is intentional, like:
foo(StringRef name);
foo(StringRef name_ref) {
string name = cleanup(name_ref);
...
}
Or semantically unimportant, like:
foo(StringRef full_name);
foo(StringRef name) { ... }
There are other matching names we won't recognise (e.g. syns vs synonyms) but
this catches many that we see in practice, and gives people a systematic
workaround.
The old behavior is available as a 'Strict' option.

Summary:
An AST-based approach is used to retrieve the document symbols rather than an
in-memory index query. The index is not an ideal fit to achieve this because of
the file-centric query being done here whereas the index is suited for
project-wide queries. Document symbols also includes more symbols and need to
keep the order as seen in the file.

These checks flag use of random number generators with poor seeds that would possibly lead to degraded random number generation.
Patch by Borsik Gábor
llvm-svn: 336301
Summary:
For completion items that would trigger include insertions (i.e. index symbols
that are not #included yet), add a visual indicator "+" before the completion
label. The inserted headers will appear in the completion detail.
Open to suggestions for better visual indicators; "+" was picked because it
seems cleaner than a few other candidates I've tried (*, #, @ ...).
The displayed header would be like a/b/c.h (without quote) or <vector> for system
headers. I didn't add quotation or "#include" because they can take up limited
space and do not provide additional information after users know what the
headers are. I think a header alone should be obvious for users to infer that
this is an include header..
To align indentation, also prepend ' ' to labels of candidates that would not
trigger include insertions (only for completions where index results are
possible).
