[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.
