Simon Pilgrim 7e3b22758d Revert rL365355 : [Syntax] Introduce syntax trees
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.

Ilya Biryukov 5e69f27ef7 [Syntax] Do not glue multiple empty PP expansions to a single mapping
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.

Ilya Biryukov ddd5d5dbc8 [Syntax] Introduce TokenBuffer, start clangToolingSyntax library
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.
