Yitzhak Mandelbaum 6f8f5cb77e [libTooling] Add function to Transformer to create a no-op edit.
This functionality is commonly needed in clang tidy checks (based on
transformer) that only print warnings, without suggesting any edits. The no-op
edit allows the user to associate a diagnostic message with a source location.

Alex Richardson 66a3b9073a [clang-format] Drop clangFrontend dependency for FormatTests
This allows building the clang-format unit tests in only 657 ninja steps
rather than 1257 which allows for much faster incremental builds after a
git pull.

Alex Richardson a2214757e2 Move clang/Tooling/Core/Lookup.h to clang/Tooling/Refactoring/Lookup.h
This allows removing the clangAST dependency from libclangToolingCore and
therefore allows clang-format to be built without depending on clangAST.
Before 1166 files had to be compiled for clang-format, now only 796.

Yitzhak Mandelbaum 65cb4fdd69 [libTooling] Change `after` range-selector to operate only on source ranges
Currently, `after` fails when applied to locations in macro arguments.  This
change projects the subrange into a file source range and then applies `after`.

Stefan Pintilie 0741a2c9ca [Clang][unittests][NFC] Break up test in Callbacks.cpp
The Callbacks.cpp test was taking a long time to compile on some build bots
causing timeouts. This patch splits up that test into five separate cpp
files and a header file.

Eduardo Caldas 5011d43108 Migrate Declarators to use the List API
After this change all nodes that have a delimited-list are using the
`List` API.

Implementation details:
Let's look at a declaration with multiple declarators:
`int a, b;`
To generate a declarator list node we need to have the range of
declarators: `a, b`:
However, the `ClangAST` actually stores them as separate declarations:
`int a   ;`
`int    b;`
We solve that by appropriately marking the declarators on each separate
declaration in the `ClangAST` and then for the final declarator `int
b`, shrinking its range to fit to the already marked declarators.

Eduardo Caldas 66bcb14312 [SyntaxTree][Synthesis] Fix: `deepCopy` -> `deepCopyExpandingMacros`.
There can be Macros that are tagged with `modifiable`. Thus verifying
`canModifyAllDescendants` is not sufficient to avoid macros when deep
copying.

We think the `TokenBuffer` could inform us whether a `Token` comes from
a macro. We'll look into that when we can surface this information
easily, for instance in unit tests for `ComputeReplacements`.

These arguments are not dependency file generation related, and these

Eduardo Caldas c655d80815 [SyntaxTree] Extend the syntax tree dump to also cover `NodeRole`
We should see `NodeRole` information in the dump because that exposes how the
accessors will behave.

Functional changes in the dump:
* Surround Leaf tokens with `'`
* Append `Node` dumps with `NodeRole` information, except for unknown roles
* Append marks to `Node` dumps, instead of prepending

Non-functional changes:
* `::dumpTokens(llvm::raw_ostream, ArrayRef<syntax::Token>, const
SourceManager &SM)` always received as parameter a `syntax::Token *`
pointing to `Leaf::token()`. Changed the function to
`dumpLeaf(llvm::raw_ostream, syntax::Leaf *, const SourceManager&)`
* `dumpTree` acted on a Node, rename to `dumpNode`
