Summary:
Most of the statements mirror the ones provided by clang AST.
Major differences are:
- expressions are wrapped into 'ExpressionStatement' instead of being
a subclass of statement,
- semicolons are always consumed by the leaf expressions (return,
expression satement, etc),
- some clang statements are not handled yet, we wrap those into an
UnknownStatement class, which is not present in clang.
We also define an 'Expression' and 'UnknownExpression' classes in order
to produce 'ExpressionStatement' where needed. The actual implementation
of expressions is not yet ready, it will follow later.

Summary:
Returns the first token in every mapping where the token is an identifier.
This API is required to be able to highlight macro expansions in clangd.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Summary:
While useful as a sentinel value when iterating over tokens, having
'eof' in the tree, seems to do more harm than good.

Summary:
A tooling-focused alternative to the AST. This commit focuses on the
memory-management strategy and the structure of the AST.
More to follow later:
- Operations to mutate the syntax trees and corresponding textual
replacements.
- Mapping between clang AST nodes and syntax tree nodes.
- More node types corresponding to the language constructs.

Summary:
This change makes sure we have a single mapping for each macro expansion,
even if the result of expansion was empty.
To achieve that, we take information from PPCallbacks::MacroExpands into
account. Previously we relied only on source locations of expanded tokens.

Summary:
TokenBuffer stores the list of tokens for a file obtained after
preprocessing. This is a base building block for syntax trees,
see [1] for the full proposal on syntax trees.
This commits also starts a new sub-library of ClangTooling, which
would be the home for the syntax trees and syntax-tree-based refactoring
utilities.
