cmd/asm: rename arm64 instructions LDANDx to LDCLRx

The LDANDx instructions were misleading because they correspond to the
mnemonic LDCLRx as defined in the Arm Architecture Reference Manual for
Armv8. This changes the assembler to use the same mnemonic as the GNU
assembler and the manual.

The instruction has the form:

LDCLRx Rs, (Rb), Rt: *Rb -> Rt, Rs AND NOT(*Rb) -> *Rb
