    aarch64: Mark clearbhb as a pseudo instruction
    
    This was an early name for the clrbhb hint instruction.  Some software
    was written with the old name before it was renamed, so we support it
    for assembly but should never use it in disassembly.
    
    This patch has no functional change, because we already pick (by
    default) the last matching alias in the opcode table, and clrbhb is
    listed later than clearbhb.
