toHalfOpenFileRange() already handles translating macro locations to

This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
getFileLoc() is guaranteed to return a file loc, and getSpellingLoc()
on a file loc is a no-op.

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:
https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716
This is a cleanup of all llvm-qualified-auto findings.
This patch was created by automatically applying the fixes from
clang-tidy.

Xcode uses `#pragma mark -` to draw a divider in the outline view
and `#pragma mark Note` to add `Note` in the outline view. For more
information, see https://nshipster.com/pragma/.
Since the LSP spec doesn't contain dividers for the symbol outline,
instead we treat `#pragma mark -` as a group with children - the
decls that come after it, implicitly terminating when the symbol's
parent ends.
The following code:
```
@implementation MyClass
- (id)init {}
- (int)foo;
@end
```
Would give an outline like
```
MyClass
> Overrides
> init
> Public Accessors
> foo
```

Dummy is a word with inappropriate associations. This patch updates the
references to it in clangd code base with more precise ones.
The only user-visible change is the default variable name used when extracting a
variable. It will be named as `placeholder` from now on.

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

NameMatch could be a float close to zero, in such cases we were
dividing by zero and moreover propogating a "NaN" to clients, which is invalid
per JSON.
This fixes the issue by only using Quality scores whenever the NameMatch is low,
as we do in CodeCompletion ranking.

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.

The protocol doesn't really incorporate ranking.
As with code completion, most clients respect what the server sends, but
VSCode re-ranks items, with predictable results.
See https://github.com/clangd/vscode-clangd/issues/81
There's no filterText field so we may be unable to construct a good workaround.
But expose the score so we may be able to do this on the client in future.

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.
`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.
This much better reflects what is (now) in this header.
Maybe a rename to ParsedTU would be an improvement, but that's a much
more invasive change and life is too short.
ClangdUnit is dead, long live ClangdUnitTests!

The hope is this will catch a few patterns with repetition:
SomeClass* S = ^SomeClass::Create()
int getFrobnicator() { return ^frobnicator_; }
// discard the factory, it's no longer valid.
^MyFactory.reset();
Without triggering antipatterns too often:
return Point(x.first, x.^second);
I'm going to gather some data on whether this turns out to be a win overall.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

The new guideline is to qualify with 'llvm::' explicitly both in
'.h' and '.cpp' files. This simplifies moving the code between
header and source files and is easier to keep consistent.

Summary:
File paths in URIForFile can come from index or local AST. Path from
index goes through URI transformation and the final path is resolved by URI
scheme and could be potentially different from the original path. Hence, we
should do the same transformation for all paths. We do this in URIForFile, which
now converts a path to URI and back to a canonicalized path.
