    [alpha] adjust MEM alignment for block move [PR115459]

    Before issuing loads or stores for a block move, adjust the MEM
    alignments if analysis of the addresses enabled the inference of
    stricter alignment.  This ensures that the MEMs are sufficiently
    aligned for the corresponding insns, which avoids trouble in case of
    e.g. substitutions into SUBREGs.
