Stephen Kelly d147cea3b9 Move TraversalKind enum to ast_type_traits
Summary:
Make it usable outside of ASTMatchFinder.  This will make it possible to
use this enum to control whether certain implicit nodes are skipped
while AST dumping for example.

Ben Hamilton a282bde69e [ASTMatchers] Introduce Objective-C matchers `isClassMessage`, `isClassMethod`, and `isInstanceMethod`
Summary:
isClassMessage is an equivalent to isInstanceMessage for ObjCMessageExpr, but matches message expressions to classes.

isClassMethod and isInstanceMethod check whether a method declaration (or definition) is for a class method or instance method (respectively).

Tom Roeder 521f004e99 [ASTImporter] Add support for importing ChooseExpr AST nodes.
Summary:
This allows ASTs to be merged when they contain ChooseExpr (the GNU
__builtin_choose_expr construction). This is needed, for example, for
cross-CTU analysis of C code that makes use of __builtin_choose_expr.

The node is already supported in the AST, but it didn't have a matcher
in ASTMatchers. So, this change adds the matcher and adds support to
ASTImporter.

This was originally reviewed and approved in
https://reviews.llvm.org/D58292 and submitted as r354832. It was
reverted in r354839 due to failures on the Windows CI builds.

This version fixes the test failures on Windows, which were caused by
differences in template expansion between versions of clang on different
OSes. The version of clang built with MSVC and running on Windows never
expands the template in the C++ test in ImportExpr.ImportChooseExpr in
clang/unittests/AST/ASTImporter.cpp, but the version on Linux does for
the empty arguments and -fms-compatibility.

So, this version of the patch drops the C++ test for
__builtin_choose_expr, since that version was written to catch
regressions of the logic for isConditionTrue() in the AST import code
for ChooseExpr, and those regressions are also caught by
ASTImporterOptionSpecificTestBase.ImportChooseExpr, which does work on
Windows.

Chandler Carruth 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.

Eric Fiselier 5cdc2cda28 [AST] Store "UsesADL" information in CallExpr.
Summary:
Currently the Clang AST doesn't store information about how the callee of a CallExpr was found. Specifically if it was found using ADL.

However, this information is invaluable to tooling. Consider a tool which renames usages of a function. If the originally CallExpr was formed using ADL, then the tooling may need to additionally qualify the replacement.
Without information about how the callee was found, the tooling is left scratching it's head. Additionally, we want to be able to match ADL calls as quickly as possible, which means avoiding computing the answer on the fly.

This patch changes `CallExpr` to store whether it's callee was found using ADL. It does not change the size of any AST nodes.

Fangrui Song 5313327f61 Add explicit dependency on clangSerialization for a bunch of components to fix -DBUILD_SHARED_LIBS=on build
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.
