[clang-doc] add support for concepts (#144430)
Add support for documenting concepts. This handles concepts and constraints on function and class templates.

Atomic constraints are not considered yet. We don't order constraints based on their conjunctive or disjunctive properties.

Refactor clang doc comment structure (#142273)
This patch refactors CommentKind handling in clang-doc by introducing a
strongly typed enum class for better type safety and clarity. It updates
all relevant places, including YAML traits and serialization, to work
with the new enum. Additionally, it enhances the Mustache-based HTML
generation by fully supporting all comment kinds, ensuring accurate
structured rendering of comment blocks. The changes simplify future
maintenance, improve robustness by eliminating unchecked defaults, and
ensure consistency between generators.

[clang-doc] Add start and end line numbers (#137732)
This patch adds start and end line numbers to clang-doc. Currently
clang-doc only encodes the start line numbers of records, struct, etc.
This patch adds start and end line number to clang-doc bitcode which is
passed to the generator. This will be used by the mustache backend to
generate line ranges. Based on the orginal patch in #135081.

4a68babd99 [clang-doc] Add template support.
Reads template information from the AST and adds template parameters and
specialization information to the corresponding clang-doc structures.

Add a "QualName" to the Reference struct which includes the full
qualified type name. The Reference object represents a link in the
HTML/MD generators so is based on the unqualified name. But this does
not encode C-V qualifiers or template information that decorate the
name. The new QualName member encodes all of this information and also
makes it easier for the generators or downsteam YAML consumers to
generate the full name (before they had to process the "Path").

In test code that was changed, remove made-up paths to built-in types
like "int". In addition to slightnly cleaning up the code, these types
do not have paths in real execution, and generating incorrect references
to nonexistant data may complicate future changes in the generators.

Convert llvm::Optional to std::optional (YAML library requires this for
the new usage, and this makes everything consistent according to the
llvm::Optional -> std::optional transition).

7b8c7e0212 [clang-doc] Move file layout to the generators.
Previously file naming and directory layout was handled on a per Info
object basis by ClangDocMain and the generators blindly wrote to the
files given. This means all generators must use the same file layout and
caused problems where multiple objects mapped to the same file. The
object collision problem happens most easily with template
specializations because the template parameters are not part of the
"name".

This patch moves the responsibility for output file organization to the
generators. Currently HTML and MD use the same structure as before. But
they now collect all objects that map to a given file and combine them,
avoiding the corruption problems.

Converts the YAML generator to naming files based on USR in one
directory. This is easier for downstream tools to manage and avoids the
naming problems with template specializations. Since this change
requires backward-incompatible output changes to referenced files anyway
(since each one is now an array), this is a good time to introduce this
change.

21fb70c6ab [clang-doc] Add typedef/using information.
Read typedef and "using" type alias declarations and serialize into the
internal structures. Emit this information in the YAML output. The HTML
and MD generators are unchanged.

Separate out the logic to create the parent namespace or record object
and insert the newly created child into it. This logic was previously
duplicated for every "info" type and is now shared.

To help this, a struct containing the child vectors was separated out so
children can be added generically and without having too many templates.

A small change was made to populateParentNamespaces() to allow using
types that aren't themselves DeclContexts (typedefs are the first
example of this).

0afc60858e [clang-doc] Clean up *Info constructors.
The *Info object (for the copy of the AST") constructors had many duplicated variants. Many of the variants seemed to be in an attempt to avoid default arguments. But default arguments are not prohibited and using them allows most of the variants to be removed which improves readability.

Remove the IsInGlobalNamespace flag on a Reference. This is set when the path is empty, and only read once in the HTML generator with the identical condition. The constructor cleanup exposed a problem where this was set to false when the constructor with no path was used, but true when the path was set to empty.

There should be no observable change with the exception that IsInGlobalNamespace is no longer emitted in YAML.

eaa7b324d5 [clang-doc] Add support for explicitly typed enums
Add support for explicitly typed enums:
  enum Foo : unsigned { ... };
to the internal representation and to the YAML output.

Add support for getting the value of an enum constant, as well as accessing the original expression that produced it. This changes the YAML output of enums from an array of strings for the enum members to an array of dictionaries. These dictionaries now report the name, value, and original expression.

The markdown and HTML outputs are unchanged, they still output the name from the new enhanced internal schema.

6a29ae4bde [clang-doc] Fix bitcode writer for access specifiers
Bitcode writer was not emitting the corresponding record for the Access attribute of a FunctionInfo. This has been added.
AS_none was being used as the default value for any AcesssSpecifier attribute
(in FunctionInfo and MemberTypeInfo), this has been changed to AS_public
because this is the enum value that evaluates to 0.
The bitcode writer doesn't write values that are 0 so if an attribute
was set to AS_public, this value is not written and after reading the
bitcode it would have the default value which is AS_none. This is why
the default value is now AS_public.

15e468e0d5 [clang-doc] Fix link generation
Before making a link to a reference it is required to check that the
reference has a path (eg. primitives won't have paths).
This was done by checking if the path was empty; that worked because
when generating paths the outdirectory was included, so if the path was
assigned it had that outdirectory at least.
The path generation was changed, it's now only the composite of the
namespaces without the outdirectory. So if the info is in the global
namespace the path would be empty and the old check wouldn't work as expected.
A new attribute has been added to the Reference struct that indicates if
the info's parent is the global namespace.
Paths generation now fails if the path is empty and if the info
is not in the global namespace.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.
