Summary:
Currently AST only contains the location for `decltype` keyword,
therefore we were skipping expressions inside decltype while building selection
tree.
This patch extends source range in such cases to contain the expression as well.
A proper fix would require changes to Sema and DecltypeTypeLoc to contain these
location information.

Summary:
With this patch the `findReferences` API will return Xref for macros.
If the symbol under the cursor is a macro then we collect the references to it from:
1. Main file by looking at the ParsedAST. (These were added to the ParsedAST in https://reviews.llvm.org/D70008)
2. Files other than the mainfile by looking at the:
* static index (Added in https://reviews.llvm.org/D70489)
* file index (Added in https://reviews.llvm.org/D71406)
This patch collects all the xref from the above places and outputs it in `findReferences` API.

Summary:
LSP requires diagnostics to lay inside main file. In clangd we keep
diagnostics in three different cases:
- already in main file
- adjusted to a header included in main file
- has a note covering some range in main file
In the last case, we were not adjusting the diagnostics range to be in main
file, therefore these diagnostics ended up pointing some arbitrary locations.
This patch fixes that issue by adjusting the range of diagnostics to be the
first note inside main file when converting to LSP.

Differential Revision: https://reviews.llvm.org/D64305
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

The revert describes a test failure without details, after offline
discussion this in in a private/unsupported build system and doesn't
seem to reflect a real upstream bug.
Summary:
Clangd didn't fill documentation for `auto` when it wasn't available in
index. Also it wasn't showing any documentations for implicit instantiations.
This patch ensures auto and normal decl case behaves in the same way and also
makes use of the explicit template specialization while fetching comments for
implicit instantiations.

Summary:
Clangd normally skips inline and anon namespaces while printing nested name
specifiers. It also drops any tag specifiers since we make use of `HoverInfo::Kind`
instead of some text in `HoverInfo::Name`
There was a bug causing us to print innermost inline/anon namespace, this patch
fixes that by skipping those.
Also changes printing and kind detection of deduced types to be similar to decl
case.
Also improves printing for lambdas, currently clangd prints lambdas as
`(anonymous class)`, we can improve it by at least printing `(lambda)`
instead.

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.

`findName` was always used in conjuction with `spellingLocIfSpelled`.
This patch replaces patterns of the form:
spellingLocIfSpelled(findName(&ND), SM)
With a new helper function:
nameLocation(ND, SM)
And removes `spellingLocIfSpelled` and `findName`. Both are never used
anywhere else and the latter is an equivalent of `Decl::getLocation` if
we ever need it again.
Summary:
Currently we only delete function body from declaration, in addition to
that we should also drop ctor initializers.
Unfortunately CXXConstructorDecl doesn't store the location of `:` before
initializers, therefore we make use of token buffer to figure out where to start
deletion.

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.
