x86/alternative: Complicate optimize_nops() some more
Because:
SMP alternatives: ffffffff810026dc: [2:44) optimized NOPs: eb 2a eb 28 cc cc
cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc
cc cc cc cc cc cc cc cc cc cc cc cc cc
is quite daft, make things more complicated and have the NOP runlength
detection eat the preceding JMP if they both end at the same target.
SMP alternatives: ffffffff810026dc: [0:44) optimized NOPs: eb 2a cc cc cc cc
cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc
