cstool -d x64 "4c 85 7d 30" doesn't give the correct register reads after sync with LLVM 7.0.1

[jrmuizel]

Before:

 0  4c 85 7d 30                                      test	qword ptr [rbp + 0x30], r15
	Prefix:0x00 0x00 0x00 0x00
	Opcode:0x85 0x00 0x00 0x00
	rex: 0x4c
	addr_size: 8
	modrm: 0x7d
	disp: 0x30
	sib: 0x0
	op_count: 2
		operands[0].type: MEM
			operands[0].mem.base: REG = rbp
			operands[0].mem.disp: 0x30
		operands[0].size: 8
		operands[0].access: READ
		operands[1].type: REG = r15
		operands[1].size: 8
		operands[1].access: READ
	Registers read: rbp r15
	Registers modified: rflags
	EFLAGS: MOD_SF MOD_ZF MOD_PF RESET_OF RESET_CF UNDEF_AF

after

 0  4c 85 7d 30                                      test	qword ptr [rbp + 0x30], r15
	Prefix:0x00 0x00 0x00 0x00
	Opcode:0x85 0x00 0x00 0x00
	rex: 0x4c
	addr_size: 8
	modrm: 0x7d
	disp: 0x30
	sib: 0x0
	op_count: 2
		operands[0].type: MEM
			operands[0].mem.base: REG = rbp
			operands[0].mem.disp: 0x30
		operands[0].size: 8
		operands[1].type: REG = r15
		operands[1].size: 8
	Registers read: rbp

The read access of r15 is not included in operands[1] and r15 doesn't show up in "Registers read"
