NOTE: This is a preliminary revision for discussion; tests have not yet been provided.

The RangeSelector library defines a combinator language for specifying source
ranges based on bound id for AST nodes.  The combinator approach follows the
design of the AST matchers.  The RangeSelectors defined here will be used in
both RewriteRule, for specifying source affected by edit, and in Stencil for
specifying source to use constructively in a replacement.

This revision extends the SourceCode library with utility functions needed by
RangeSelector.  Some of them come are copied from clang-tidy/utils/LexUtils,
since clang/Tooling can't depend on clang-tidy libraries.
