Haojian Wu 6ba1b9075d Reland "[AST] Add a new TemplateKind for template decls found via a using decl."" 
This is the template version of https://reviews.llvm.org/D114251.

This patch introduces a new template name kind (UsingTemplateName). The
UsingTemplateName stores the found using-shadow decl (and underlying
template can be retrieved from the using-shadow decl). With the new
template name, we can be able to find the using decl that a template
typeloc (e.g. TemplateSpecializationTypeLoc) found its underlying template,
which is useful for tooling use cases (include cleaner etc).

This patch merely focuses on adding the node to the AST.

Next steps:
- support using-decl in qualified template name;
- update the clangd and other tools to use this new node;
- add ast matchers for matching different kinds of template names;

clangd

clangd is a language server, and provides C++ IDE features to editors. This is not its documentation.

Communication channels

If you have any questions or feedback, you can reach community and developers through one of these channels:

Building and testing clangd

For a minimal setup on building clangd:

  • Clone the LLVM repo to $LLVM_ROOT.

  • Create a build directory, for example at $LLVM_ROOT/build.

  • Inside the build directory run: cmake $LLVM_ROOT/llvm/ -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra".

    • We suggest building in Release mode as building DEBUG binaries requires considerably more resources. You can check Building LLVM with CMake documentation for more details about cmake flags.
    • In addition to that using Ninja as a generator rather than default make is preferred. To do that consider passing -G Ninja to cmake invocation.
    • Finally, you can turn on assertions via -DLLVM_ENABLE_ASSERTS=On.

  • Afterwards you can build clangd with cmake --build $LLVM_ROOT/build --target clangd, similarly run tests by changing target to check-clangd.
