This commit fixes an internal compiler error (ICE) that could occur during recurrence vectorization. The issue was an oversight in a previous fix (PR124677) that didn’t properly guard against hitting the last statement when searching for an insertion point in the loop. This commit adds the missing guard, preventing the ICE. A new testcase was added to reproduce and verify the fix.
