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.c (hoist_guard): Always insert
new conditional after last stmt.

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

(cherry picked from commit d96bd4aade170fcd86f5f09b68b770dde798e631)
