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:
While it's perfectly reasonable for non-named decls such as
static_assert to resolve to themselves:
- nothing else ever resolves to them
- features based on references (hover, highlight, find refs etc) tend
to be uninteresting where only trivial references are possible
- returning NamedDecl is a more convenient API (we cast to it in many places)
- this aligns closer to findExplicitReferences/explicitReferenceTargets
This fixes a crash in explicitReferenceTargets: if the target is a
non-named decl then there's an invalid unchecked cast to NamedDecl.
In practice this means when hovering over e.g. a static_assert:
- before ac3f9e4842, we would show a (boring) hover card
- after ac3f9e4842, we would crash
- after this patch, we will show nothing

Summary:
The problem:
LSP specifies that Positions are between characters. Therefore when a position
(or an empty range) is used to target elements of the source code, there is an
ambiguity - should we look left or right of the cursor?
Until now, SelectionTree resolved this to the right except in trivial cases
(where there's whitespace, semicolon, or eof on the right).
This meant that it's unable to e.g. out-line `int foo^()` today.
Complicating this, LSP notwithstanding the cursor is *on* a character in many
editors (mostly terminal-based). In these cases there's no ambiguity - we must
"look right" - but there's also no way to tell in LSP.
(Several features currently resolve this by using getBeginningOfIdentifier,
which tries to rewind and supports end-of-identifier. But this relies on
raw lexing and is limited and buggy).
Precedent: well - most other languages aren't so full of densely packed symbols
that we might want to target. Bias-towards-identifier works well enough.
MS C++ for vscode seems to mostly use bias-toward-identifier too.
The problem with this solution is it doesn't provide any way to target some
things such as the constructor call in Foo^(bar());
Presented solution:
When an ambiguous selection is found, we generate *both* possible selection
trees. We try to run the feature on the rightward tree first, and then on the
leftward tree if it fails.
This is basically do-what-I-mean, the main downside is the need to do this on
a feature-by-feature basis (because each feature knows what "fail" means).
The most complicated instance of this is Tweaks, where the preferred selection
may vary tweak-by-tweak.
Wrinkles:
While production behavior is pretty consistent, this introduces some
inconsistency in testing, depending whether the interface we're testing is
inside or outside the "retry" wrapper.
In particular, for many features like Hover, the unit tests will show production
behavior, while for Tweaks the harness would have to run the loop itself if
we want this.

Summary:
When moving function definitions to a different context, the function
name might need a different spelling, for example in the header it might be:
```
namespace a {
void foo() {}
}
```
And we might want to move it into a context which doesn't have `namespace a` as
a parent, then we must re-spell the function name, i.e:
```
void a::foo() {}
```
This patch implements a version of this which ignores using namespace
declarations in the source file.

Currently define inline action fully qualifies any names in the

This patch tries to improve the situation by dropping any name
specifiers shared by function and names spelled in the body. For example
if you are moving definition of a function in namespace clang::clangd,
and body has any decl's coming from clang or clang::clangd namespace,
those qualifications won't be added since they are redundant.
It also drops any qualifiers that are visible in target context.

Summary:
This is mostly mechanical, with a few exceptions:
- getDeducedType moved into AST.h where it belongs. It now takes
ASTContext instead of ParsedAST, and avoids using the preprocessor.
- hover now uses SelectionTree directly rather than via
getDeclAtPosition helper
- hover on 'auto' used to find the decl that contained the 'auto' and
use that to set Kind and documentation for the hover result.
Now we use targetDecl() to find the decl matching the deduced type instead.
This changes tests, e.g. 'variable' -> class for auto on lambdas.
I think this is better, but the motivation was to avoid depending on
the internals of DeducedTypeVisitor. This functionality is removed
from the visitor.

Summary:
Whitespace and comments are a clear bugfix: selecting some
comments/space near a statement doesn't mean you're selecting the
surrounding block.
Semicolons are less obvious, but for similar reasons: these tokens
aren't actually claimed by any AST node (usually), so an AST-based model
like SelectionTree shouldn't take them into account.
Callers may still sometimes care about semis of course:
- when the selection is an expr with a non-expr parent, selection of
the semicolon indicates intent to select the statement.
- when a statement with a trailing semi is selected, we need to know
its range to ensure it can be removed.
SelectionTree may or may not play a role here, but these are separate questions
from its core function of describing which AST nodes were selected.
The mechanism here is the TokenBuffer from syntax-trees. We use it in a
fairly low-level way (just to get boundaries of raw spelled tokens). The
actual mapping of AST nodes to coordinates continues to use the (fairly
mature) SourceLocation based logic. TokenBuffer/Syntax trees
don't currently offer an alternative to getFileRange(), I think.

However informally +, *, etc are usually (mathematically) associative and users
consider these subexpressions.
We detect these and in simple cases support extracting the partial expression.
As well as builtin associative operators, we assume that overloads of them
are associative and support those too.

Summary:
After rL366893, the annoate tweak is not activated when we select the
whole file (the commonAncestor is TUDecl but we intend to return null).
This patch fixes this, and also avoid traversing the TUDecl.

Summary:
Previously TranslationUnitDecl would never be selected.
This means root() is never null, and returns a reference.
commonAncestor() is in principle never null also, but returning TUDecl
here requires tweaks to be careful not to traverse it (this was already
possible when selecting multiple top-level decls, and there are associated bugs!)
Instead, never allow commonAncestor() to return TUDecl, return null instead.

Add a tweak for clangd to replace an auto keyword to the deduced type.
This way a user can declare something with auto and then have the
IDE/clangd replace auto with whatever type clangd thinks it is. In case
of long/complext types this makes is reduces writing effort for the
user.
The functionality is similar to the hover over the auto keyword.
Example (from the header):
```
/// Before:
/// auto x = Something();
/// ^^^^
/// After:
/// MyClass x = Something();
/// ^^^^^^^
```

Summary:
GetTypePtr requires that the type should not be null, otherwise we hit
an assertion, we should use getTypePtrOrNull instead.

Summary:
Previously, when we rename a macro, we get an error message of "there is
no symbol found".
This patch improves the message of this case (as we don't support macros).

Summary:
Failing case:
```
#include "foo.h"
void fo^o() {}
```
getRenameDecl() returns the decl of the symbol under the cursor (which is
in the current main file), instead, we use the canonical decl to determine
whether a symbol is declared in #included header.

Summary:
Previously, we performed rename for all kinds of symbols (local, global).
This patch narrows the scope by only renaming symbols not being used
outside of the main file (with index asisitance). Renaming global
symbols is not supported at the moment (return an error).

Summary:
This introduces a few new concepts:
- tweaks have an Intent (they don't all advertise as refactorings)
- tweaks may produce messages (for ShowMessage notification). Generalized
Replacements -> Effect.
- tweaks (and other features) may be hidden (clangd -hidden-features flag).
We may choose to promote these one day. I'm not sure they're worth their own
feature flags though.
Verified it in vim-clangd (not yet open source), curious if the UI is ok in VSCode.

Summary:
This reduces the per-check implementation burden and redundant work.
It also makes checks range-aware by default (treating the commonAncestor
as if it were a point selection should be good baseline behavior).

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.
