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.
