Extend the matchers gathering API for types to record template
parameters. The TypeLoc type hierarchy has some types which are
templates used in CRTP such as PointerLikeTypeLoc. Record the inherited
template and template arguments of types inheriting those CRTP types in
the ClassInheritance map. Because the name inherited from is now
computed, the value type in that map changes from StringRef to
std::string. This also causes the toJSON override signature used to
serialize that map to change.
Remove the logic for skipping over empty ClassData instances. Several
classes such as TypeOfExprTypeLoc inherit a CRTP class which provides
interesting locations though the derived class does not. Record it as a
class to make the locations it inherits available.
Record the typeSourceInfo accessors too as they provide access to
TypeLocs in many classes.
The existing unit tests use UnorderedElementsAre to compare the
introspection result with the expected result. Our current
implementation of google mock (in gmock-generated-matchers.h) is limited
to support for comparing a container of 10 elements. As we are now
returning more than 10 results for one of the introspection tests,
change it to instead compare against an ordered vector of pairs.
Because a macro is used to generate API strings and API calls, disable
clang-format in blocks of expected results. Otherwise clang-format
would insert whitespaces which would then be compared against the
introspected strings and fail the test.
Introduce a recursion guard in the generated code. The TypeLoc class
has IgnoreParens() API which by default returns itself, so it would
otherwise recurse infinitely.

Generate a json file containing descriptions of AST classes and their

after this change is reviewed, as this change is mostly about

Also in this version, the platforms/cmake configurations are excluded as

break on any platform causes a revert of the entire feature. This way,
the `OR WIN32` can be removed in a future commit and if it breaks the

Summary:
As discussed previously when landing patch for OpenMP in Flang, the idea is
to share common part of the OpenMP declaration between the different Frontend.
While doing this it was thought that moving to tablegen instead of Macros will also
give a cleaner and more powerful way of generating these declaration.
This first part of a future series of patches is setting up the base .td file for
DirectiveLanguage as well as the OpenMP version of it. The base file is meant to
be used by other directive language such as OpenACC.
In this first patch, the Directive and Clause enums are generated with tablegen
instead of the macros on OMPConstants.h. The next pacth will extend this
to other enum and move the Flang frontend to use it.

that specifies the directive and one allowed clause explicitly instead
of a dedicated macro per directive.

not once per directive.

This is a more thorough fix of rC348911.
The story about -DBUILD_SHARED_LIBS=on build after rC348907 (Move PCHContainerOperations from Frontend to Serialization) is:
1. libclangSerialization.so defines PCHContainerReader dtor, ...
2. clangFrontend and clangTooling define classes inheriting from PCHContainerReader, thus their DSOs have undefined references on PCHContainerReader dtor
3. Components depending on either clangFrontend or clangTooling cannot be linked unless they have explicit dependency on clangSerialization due to the default linker option -z defs. The explicit dependency could be avoided if libclang{Frontend,Tooling}.so had these undefined references.
This patch adds the explicit dependency on clangSerialization to make them build.

Summary:
This defines a `clang::tooling::ToolExecutor` interface that can be extended to support different execution plans including standalone execution on a given set of TUs or parallel execution on all TUs in a codebase.
In order to enable multiprocessing execution, tool actions are expected to output result into a `ToolResults` interface provided by executors. The `ToolResults` interface abstracts how results are stored e.g. in-memory for standalone executions or on-disk for large-scale execution.
New executors can be registered as `ToolExecutorPlugin`s via the `ToolExecutorPluginRegistry`. CLI tools can use `createExecutorFromCommandLineArgs` to create a specific registered executor according to the command-line arguments.
This patch also implements `StandaloneToolExecutor` which has the same behavior as the current `ClangTool` interface, i.e. execute frontend actions on a given set of TUs. At this point, it's simply a wrapper around `ClangTool` at this point.
This is still experimental but expected to replace the existing `ClangTool` interface so that specific tools would not need to worry about execution.
