On systems like ARM, where the non-addressable bits of a pointer
value may be used for metadata (ARMv8.3 pointer authentication, or
Type Byte Ignore), those bits need to be cleared before the address
points to a valid memory location. Add a call to the target's ABI
to clear those from address expression arguments to the lldb
commands (e.g. `disassemble -a`).
