    bpf: fix index register for classic BPF indirect loads
    
    Classic BPF filters using a variable offset into the packet, such as
    "tcp[tcpflags] & tcp-syn != 0" or "tcp[0:4] = ...", read the wrong bytes.
    
    The indirect loads ldb/ld [x + k] were handled in the same case as the
    arithmetic instructions, which take the source register from
    BPF_SRC(code), that is bit 0x08. In a load opcode that bit is part of
    the size field, not a K/X selector, so BPF_LD|BPF_IND|BPF_B (0x50) and
    BPF_LD|BPF_IND|BPF_W (0x40) both yield BPF_K and the index register
    becomes R0 (A) instead of R7 (X). The halfword form works only because
    BPF_H and BPF_X are both 0x08.
    
    Give the indirect loads their own case next to the absolute loads and
    emit X as the index register. The interpreter and the JITs already
    take the index from src_reg, so this fixes all engines.
