[PATCH] D62412: [LibTooling] Fix unused-variable warning after r361647.

[Yitzhak Mandelbaum via Phabricator via cfe-commits]

ymandel created this revision.
ymandel added a reviewer: ilya-biryukov.
Herald added a project: clang.

A range-for was added in r361647 where the range variable was only used in an
assertion.  As a result, it warned for Release builds. This revision
restructures the assertion to avoid the problem.
