    [arm] Automatically enable CRC instructions on supported ARMv8-A CPUs.
    
    2016-09-07  Richard Earnshaw  <rearnsha@arm.com>
    
    	* opcode/arm.h (ARM_ARCH_V8A_CRC): New architecture.
    
    2016-09-07  Richard Earnshaw  <rearnsha@arm.com>
    
    	* config/tc-arm.c ((arm_cpus): Use ARM_ARCH_V8A_CRC for all
    	ARMv8-A CPUs except xgene1.
