    tree-optimization/113796 - if-conversion and ranges

    The following makes sure to wipe range info before folding the
    COND_EXPRs we insert as part of replacing PHI nodes when combining
    blocks in the if-conversion pass.

            * tree-if-conv.cc (combine_blocks): Wipe range-info before
            replacing PHIs and inserting predicates.

            * gcc.dg/torture/pr113796.c: New testcase.
