    tree-optimization/112282 - wrong-code with ifcvt hoisting

    The following avoids hoisting of invariants from conditionally
    executed parts of an if-converted loop.  That now makes a difference
    since we perform bitfield lowering even when we do not actually
    if-convert the loop.  if-conversion deals with resetting flow-sensitive
    info when necessary already.

            PR tree-optimization/112282
            * tree-if-conv.cc (ifcvt_hoist_invariants): Only hoist from
            the loop header.

            * gcc.dg/torture/pr112282.c: New testcase.=
