[PATCH] D34419: Make sure TraverseInitListExpr visits InitListExpr exactly twice

[Stephan Bergmann via Phabricator via cfe-commits]

sberg created this revision.

... once each for the syntactic and semantic form. Without this fix, behavior of the newly added tests would have been

InitListExprIsPreOrderVisitedTwice:
 syntactic: 1
 semantic:  2

InitListExprIsPostOrderVisitedTwice:
 syntactic: 0
 semantic:  1

InitListExprIsPreOrderNoQueueVisitedTwice:
 syntactic: 1
 semantic:  2

InitListExprIsPostOrderNoQueueVisitedTwice:
 syntactic: 0
 semantic:  2
