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.
