bpf: disassembler support JMP32
This patch teaches disassembler about JMP32. There are two places to update: - Class 0x6 now used by BPF_JMP32, not "unused". - BPF_JMP32 need to show comparison operands properly. The disassemble format is to add an extra "(32)" before the operands if it is a sub-register. A better disassemble format for both JMP32 and ALU32 just show the register prefix as "w" instead of "r", this is the format using by LLVM assembler.
