[PATCH] PR90424 - lowpart vector set recognition

The following makes SSA rewrite (update-address-taken) recognize sets of aligned sub-vectors in aligned position (v2qi into v16qi, but esp. v8qi into v16qi). It uses the BIT_INSERT_EXPR support for this, enabling that for vector typed values. This makes us turn for example typedef unsigned cha
