[PATCH v2 3/3] x86/kprobes: Boost more instructions from grp2/3/4/5

With the instruction decoder, we are now able to decode and recognize instructions with opcode extensions. There are more instructions in these groups that can be boosted: Group 2: ROL, ROR, RCL, RCR, SHL/SAL, SHR, SAR Group 3: TEST, NOT, NEG, MUL, IMUL, DIV, IDIV Group 4: INC, DEC (byte operation
