Next branch disassembles ARM vcmp.f64 instruction incorrectly.

Here is the result of capstone-v4:

> ./cstool -d arm '47 7B B4 EE'
 0  47 7b b4 ee  vcmp.f64	d7, d7
	ID: 285 (vcmp)
	op_count: 2
		operands[0].type: REG = d7
		operands[0].access: READ
		operands[1].type: REG = d7
		operands[1].access: READ
	Vector-data: 15
	Registers read: d7
	Registers modified: fpscr_nzcv
	Groups: vfp2 dpvfp

Here is the next branch

> ./cstool -d arm '47 7B B4 EE'
ERROR: invalid assembly code

But using armv8 works correctly:

> ./cstool -d armv8 '47 7B B4 EE' 
 0  47 7b b4 ee  vcmp.f64	d7, d7
	ID: 334 (vcmp)
	op_count: 2
		operands[0].type: REG = d7
		operands[0].access: READ
		operands[1].type: REG = d7
		operands[1].access: READ
	Vector-data: 16
	Registers read: d7
	Registers modified: fpscr_nzcv
	Groups: vfp2 dpvfp

There are many similar cases, could you please take a look ? Thank you!
