    write_pieced_value: Include transfer size in byte-wise check

    In write_pieced_value, when checking whether the data can be transferred

    byte-wise, the current logic verifies the source- and destination offsets

    to be byte-aligned, but not the transfer size.  This is fixed.

    gdb/ChangeLog:

            * dwarf2loc.c (write_pieced_value): Include transfer size in

            byte-wise check.
