    tree-optimization/107686 - fix bitfield ref through vec_unpack optimiza=
tion

    The following propely restricts the bitfield access to integral types
    when we look through VEC_UNPACK with the intent to emit a widening
    conversion.

            PR tree-optimization/107686
            * tree-ssa-forwprop.cc (optimize_vector_load): Restrict
            VEC_UNPACK support to integral typed bitfield refs.

            * gcc.dg/pr107686.c: New testcase.
