    -finline-stringops: check base blksize for memset [PR112778]

    The recently-added logic for -finline-stringops=memset introduced an
    assumption that doesn't necessarily hold, namely, that
    can_store_by_pieces of a larger size implies can_store_by_pieces by
    smaller sizes.  Checks for all sizes the by-multiple-pieces machinery
    might use before committing to an expansion pattern.
