Reorganize AST traversal utility code Define TIntermTraverser and TIntermLValueTrackingTraverser in a separate header file. hash() function is moved out from TIntermTraverser as it is not related to the core functionality of traversing and transforming ASTs. Also reorganize some traversers to follow common conventions: - Intermediate output is now in OutputTree.h/.cpp - Max tree depth check is now in IsASTDepthBelowLimit.h/.cpp BUG=angleproject:1490 TEST=angle_unittests Change-Id: Id4968aa9d4e24d0c5bac90dc147fc9f310de0184 Reviewed-on: https://chromium-review.googlesource.com/559531 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Olli Etuaho <oetuaho@nvidia.com>
