[lldb] Add "memory tag write" --end-addr option
The default mode of "memory tag write" is to calculate the
range from the start address and the number of tags given.
(just like "memory write" does)
(lldb) memory tag write mte_buf 1 2
(lldb) memory tag read mte_buf mte_buf+48
Logical tag: 0x0
Allocation tags:
[0xfffff7ff9000, 0xfffff7ff9010): 0x1
[0xfffff7ff9010, 0xfffff7ff9020): 0x2
[0xfffff7ff9020, 0xfffff7ff9030): 0x0
This new option allows you to set an end address and have
the tags repeat until that point.
(lldb) memory tag write mte_buf 1 2 --end-addr mte_buf+64
(lldb) memory tag read mte_buf mte_buf+80
Logical tag: 0x0
Allocation tags:
[0xfffff7ff9000, 0xfffff7ff9010): 0x1
[0xfffff7ff9010, 0xfffff7ff9020): 0x2
[0xfffff7ff9020, 0xfffff7ff9030): 0x1
[0xfffff7ff9030, 0xfffff7ff9040): 0x2
[0xfffff7ff9040, 0xfffff7ff9050): 0x0
This is implemented using the QMemTags packet previously
added. We skip validating the number of tags in lldb and send
them on to lldb-server, which repeats them as needed.
Apart from the number of tags, all the other client side checks
remain. Tag values, memory range must be tagged, etc.
