    tree-optimization/112320 - bougs debug IL after SCCP

    The following addresses wrong debug IL created by SCCP rewriting stmts
    to defined overflow.  I addressed another inefficiency there but
    needed to adjust the API of rewrite_to_defined_overflow for this
    which is now taking a stmt iterator for in-place operation and a
    stmt for sequence producing because gsi_for_stmt doesn't work for
    stmts not in the IL.

            PR tree-optimization/112320
            * gimple-fold.h (rewrite_to_defined_overflow): New overload
            for in-place operation.
            * gimple-fold.cc (rewrite_to_defined_overflow): Add stmt
            iterator argument to worker, define separate API for
            in-place and not in-place operation.
            * tree-if-conv.cc (predicate_statements): Simplify.
            * tree-scalar-evolution.cc (final_value_replacement_loop):
            Likewise.
            * tree-ssa-ifcombine.cc (pass_tree_ifcombine::execute): Adjust.
            * tree-ssa-reassoc.cc (update_range_test): Likewise.

            * gcc.dg/pr112320.c: New testcase.=
