Instead of trying to keep LastWidenRecipe updated after creating each recipe, have tryToWiden() retrieve the last recipe of the current VPBasicBlock and check if it's a VPWidenRecipe when attempting to extend its range. This ensures that such extensions, optimized to maintain the original instruction order, do so only when the instructions are to maintain their relative order. The latter does not always hold, e.g., when a cast needs to sink to unravel first order recurrence (r306884). Testcase derived from reproducer of PR34711.
