Clangd uses codecompletion limit as the limit for workspacesymbols, so
in theory this should only be an order of magnitude slower than a
codecompletion request with empty identifier (as code completion limits
the available symbols).
This is also what LSP suggests "Clients may send an empty string here to request all symbols.".
Clangd doesn't really fulfill the "all" part of that statement, but we
never do unless user set the index query limit to zero explicitly.

Browsing macro-generated symbols is confusing.
On the one hand, it seems very *useful* to be able to see the summary of
symbols that were generated.
On the other hand, some macros spew a lot of confusing symbols into the
namespace and when used repeatedly (ABSL_FLAG) can create a lot of spam
that's hard to navigate.
Design constraints:
- the macro expansion tree need not align with the AST, though it often
does in practice.
We address this by defining the nesting based on the *primary*
location of decls, rather than their ranges.
- DocumentSymbol.children[*].range should nest within DocumentSymbol.range
(This constraint is not in LSP "breadcrumbs" breaks without it)
We adjust macro ranges so they cover their "children", rather than
just the macro expansion
- LSP does not have a "macro expansion" symbolkind, nor does it allow a
symbol to have no kind. I've arbitrarily picked "null" as this is
unlikely to conflict with anything useful.
This patch makes all macros and children visible for simplicity+consistency,
though in some cases it may be better to elide the macro node.
We may consider adding heuristics for this in future (e.g. when it expands
to one decl only?) but it doesn't seem clear-cut to me.

- Categories will now show up as `MyClass(Category)` instead of
`Category` and `MyCategory()` instead of `(anonymous)` in document
symbols
- Methods will now be shown as `-selector:` or `+selector:`
instead of `selector:` to differentiate between instance and class
methods in document symbols

Currently TypePrinter lumps anonymous classes and unnamed classes in one group "anonymous" this is not correct and can be confusing in some contexts.

Previously we did not record local class declarations. Now with features like
findImplementation and typeHierarchy, we have a need to index such local
classes to accurately report subclasses and implementations of methods.

- No changes in indexing timing.
- No significant change in memory usage.
- **1%** increase in #relations.
- **0.17%** increase in #refs.
- **0.22%** increase #symbols.

This patch is a try to fix `WorkspaceSymbols.Macros` test after D93796.
If a macro definition is in the preamble section, then it appears to be in the preamble (static) index and not in the main-file (dynamic) index.
Thus, a such macro could not be found at a symbol search according to the logic that we skip symbols from the static index if the location of these symbols is inside the dynamic index files.
To fix this behavior this patch adds main file macros into the main-file (dynamic) index.

This is follow up to D93393.
Without this patch `MergedIndex::fuzzyFind()` returns stale symbols from the static index even if these symbols were removed.

This will enable queries like "clangd::" to find symbols under clangd
namespace, without requiring full "clang::clangd::" qualification.
Since Fuzzyfind performs the search under all scopes and only boosts the symbols
from relevant namespaces, we might get symbols from non-matching namespaces.
This patch chooses to drop those as they clearly do not match the query.
Fixes https://github.com/clangd/clangd/issues/550.

It is necessary to traverse children of unnamed declaration contexts
to get symbols which are currently missing in document outline, e.g.:

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
This reflects its current function better and avoids confusion with clang::DiagnosticConsumer.
The old name/constructor is left around temporarily for compatibility.
(Metagame: merging with out-of-tree changes is harder than usual this month)

Add an initial '::' qualifier to all usages of 'testing' namespace that
did not have one.
The goal is to make our code style in tests more consistent.
llvm-svn: 360026
Summary:
Motivation:
- this layout is a pain to work with
- without a common root, it's painful to express things like "disable clangd" (D61122)
- CMake/lit configs are a maintenance hazard, and the more the one-off hacks
for various tools are entangled, the more we see apathy and non-ownership.
This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.
(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).
Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.
