This means sve2 is enabled by default and the v8.8 mops (memcpy
and memset acceleration instructions) and HBC (hinted conditional
branch) extensions can be disassembled.
v9.3-a is equivalent to v8.8-a except that in v9.0-a sve2 was
enabled by default so v9.3-a includes that too.
MTE remains an optional extension, only enabled for specific CPUs.
