Fix type of bitstart in vectorizable_live_operation
This patch changes the type of the multiplier applied by
vectorizable_live_operation from unsigned_type_node to bitsizetype,
which matches the type of TYPE_SIZE and is the type expected of a
BIT_FIELD_REF bit position. This is shown by existing tests when
SVE is added.
