include:

	* opcode/arm.h: Adjust comments for ARM_EXT_V4T and ARM_EXT_V5T.
	Add ARM_EXT_V6T2, ARM_ARCH_V6T2, ARM_ARCH_V6KT2, ARM_ARCH_V6ZT2,
	and ARM_ARCH_V6ZKT2.
opcodes:
	* arm-dis.c (arm_opcodes): Document %E and %V.
	Add entries for v6T2 ARM instructions:
	bfc bfi mls strht ldrht ldrsht ldrsbt movw movt rbit ubfx sbfx.
	(print_insn_arm): Add support for %E and %V.
