    noncontiguous ifcombine: skip marking of non-SSA_NAMEs [PR117915]

    When ifcombine_mark_ssa_name is called directly, rather than by
    ifcombine_mark_ssa_name_walk, we need to check that name is an
    SSA_NAME at the caller or in the function itself.  For convenience and
    safety, I'm moving the checks from _walk to the implementation proper.
