    tree-optimization/111917 - bougs IL after guard hoisting

    The unswitching code to hoist guards inserts conditions in wrong
    places.  The following fixes this, simplifying code.

            PR tree-optimization/111917
            * tree-ssa-loop-unswitch.cc (hoist_guard): Always insert
            new conditional after last stmt.

            * gcc.dg/torture/pr111917.c: New testcase.
