LLVM JIT: Use Branch/Delay slot opcode notation to show compilation

[#ifdef LJ_SHOW_COMPILATION], we want to be more obvious that a branch
and its delay slot are related and must be done together.

To that end, branches and their delay slots are joined by a /, but the
rest is separated by a space.

Thus, this example sequence from Conker's Bad Fur Day:
  10022A78 JIT:  LW ORI OR LHU BEQ ORI BNE NOP LW ORI LUI SH LW

is now shown as:
  10022A78 JIT:  LW ORI OR LHU BEQ/ORI BNE/NOP LW ORI LUI SH LW
