If the to-be vectorized part vanishes we already redirect the versioning condition to the original loop. The following does the same in case the original loop vanishes as happened for the testcase in the bug in the past (but no longer). PR tree-optimization/106995 * tree-if-conv.cc (pass_if_conversion::execute): Also redirect the versioning condition to the original loop if this very loop vanished during CFG cleanup.
