    tree-optimization/106934 - avoid BIT_FIELD_REF of bitfields

    The following avoids creating BIT_FIELD_REF of bitfields in
    update-address-taken.  The patch doesn't implement punning to
    a full precision integer type but leaves a comment according to
    that.

            PR tree-optimization/106934
            * tree-ssa.c (non_rewritable_mem_ref_base): Avoid BIT_FIELD_REFs
            of bitfields.
            (maybe_rewrite_mem_ref_base): Likewise.

            * gfortran.dg/pr106934.f90: New testcase.
