c1 IR::verify is expensive

    Description

      c1 IR::verify is expensive. It is also run once for every block by BlockMerger. For every block all blocks are traversed - both postorder och preorder, multiple times.

      This is a debug-build problem only. But still a problem since a method that we can run in product-builds must be testable in debug-builds.
