This is needed to that clients can can make a connection between a

Ideally, quickfix-kind tweak code actions would be provided inline along

There were some left-overs (or new things) from the previous patches.
This will get us down to 0 open findings except:
clang-tidy is complaining in some files about
`warning: #includes are not sorted properly [llvm-include-order]`
however, clang-format does revert these changes.
It looks like clang-tidy and clang-format disagree there.

Auto-generated patch based on clang-tidy readability-identifier-naming.
Only some manual cleanup for `extern "C"` declarations and a GTest change was required.
I'm not sure if this cleanup is actually very useful. It cleans up clang-tidy findings to the number of warnings from clang-tidy should be lower. Since it was easy to do and required only little cleanup I thought I'd upload it for discussion.
One pattern that keeps recurring: Test **matchers** are also supposed to start with a lowercase letter as per LLVM convention. However GTest naming convention for matchers start with upper case. I would propose to keep stay consistent with the GTest convention there. However that would imply a lot of `//NOLINT` throughout these files.
To re-product this patch run:
```
run-clang-tidy -checks="-*,readability-identifier-naming" -fix -format ./clang-tools-extra/clangd
```
To convert the macro names, I was using this script with some manual cleanup afterwards:

This results in excessive memory usage and eats a lot of screen estate.
Especially in the cases with lots of nested macro calls.
This patch tries to remedy it before the release cut by suppressing the
initializers. For better UX we should probably update the expression printer to
truncate those (behind some policy).

Underscore-uglified identifiers are used in standard library implementations to
guard against collisions with macros, and they hurt readability considerably.
(Consider `push_back(Tp_ &&__value)` vs `push_back(Tp value)`.
When we're describing an interface, the exact names of parameters are not
critical so we can drop these prefixes.
This patch adds a new PrintingPolicy flag that can applies this stripping
when recursively printing pieces of AST.
We set it in code completion/signature help, and in clangd's hover display.
All three features also do a bit of manual poking at names, so fix up those too.

Support for NOLINT(BEGIN/END) blocks (implemented in D108560) is
currently costly. This patch aims to improve the performance with the
following changes:
- The use of tokenized NOLINTs instead of a series of repetitive ad-hoc
string operations (`find()`, `split()`, `slice()`, regex matching etc).
- The caching of NOLINT(BEGIN/END) block locations. Determining these
locations each time a new diagnostic is raised is wasteful as it
requires reading and parsing the entire source file.
Move NOLINT-specific code from `ClangTidyDiagnosticConsumer` to new
purpose-built class `NoLintDirectiveHandler`.

This patch adds a forward declaraiton of DynTypedNode.
DumpAST.h is relying on the forward declaration of DynTypedNode in
ASTContext.h, which is undesirable.
LLVM Programmer’s Manual strongly discourages the use of `std::vector<bool>` and suggests `llvm::BitVector` as a possible replacement.
Currently, some users of `std::vector<bool>` cannot switch to `llvm::BitVector` because it doesn't implement the `pop_back()` and `back()` functions.
To enable easy transition of `std::vector<bool>` users, this patch implements `llvm::BitVector::pop_back()` and `llvm::BitVector::back()`.

These errors are non-harmful and should be transient. They either
imply:
- compilation database returned stale results for TUs and it'll be fixed once
it's updated to match project state.
- a TUs dependencies has changed and some headers no longer exist. this should
be fixed with the next indexing cycle.
In either case the user will have some stale symbols in their index until clangd
restarts and the underlying issue is resolved. On the downside these logs are
confusing users when there's another issue.

Targets are not necessarily inserted in the order they appear in source
code. For example we could traverse overload sets, or selectively insert
template patterns after all other decls.
So order the targets before printing to make sure tests are not dependent on
such implementation details. We can also do it in production, but that might be
wasteful as we haven't seen any complaints in the wild around these orderings
yet.

Adds a option `use-dirty-preambles` to enable using unsaved in editor contents when building pre-ambles.
This enables a more seamless user experience when switching between header and implementation files and forgetting to save inbetween.
It's also in line with the LSP spec that states open files in the editor should be used instead of on the contents on disk - https://microsoft.github.io/language-server-protocol/overviews/lsp/overview/
For now the option is defaulted to off and hidden, Though I have a feeling it should be moved into the `.clangd` config and possibly defaulted to true.

During pop() we convert nodes into spans of expanded syntax::Tokens.
If we precompute a range of plausible (expanded) tokens, then we can do an
extremely cheap approximate hit-test against it, because syntax::Tokens are
ordered by pointer.
This would seem not to buy anything (we don't enter nodes unless they overlap
the selection), but in fact the spans we have are for *newly* claimed ranges
(i.e. those unclaimed by any child node).
So if you have:
{ { [[2+2]]; } }
then all of the CompoundStmts pass the hit test and are pushed, but we skip
full hit-testing of the brackets during pop() as they lie outside the range.
This is ~10x average speedup for selectiontree on a bad case I've seen
(large gtest file).

The AST doesn't track their locations, and the default behavior of attributing

When searching for AST nodes that may overlap the selection, mayHit() was only
attempting to prune nodes whose begin/end are both in the main file.
While failing to prune never gives wrong results, it hurts performance.
In GTest unit-tests, `TEST()` macros at the top level declare classes.
These were never pruned and we traversed *every* such class for any selection.
We fix this by reasoning about what tokens such a node might claim.
They must lie within its ultimate macro expansion range, so if this doesn't
overlap with the selection, we can prune the node.

New values:
- Split Dynamic into Open/Preamble
- Add Background (previously was just Unknown)
- Soon: stdlib index
This requires extending to 16 bits, which fits within the padding of Symbol.
Unfortunately we're also *serializing* SymbolOrigin as a fixed 8 bits.
Stop serializing SymbolOrigin:
- conceptually, the source is whoever indexes or *deserializes* a symbol
- deserialization takes SymbolOrigin as a parameter and stamps it on each sym
- this is a breaking format change
