Petar Jovanovic 5f3cc6c828 mips: reimplement handling of div, divu and ddivu
Previous implementation misused some opcodes, and a side effect was
dead code emission.
To reimplement handling of these instructions, three new IoPs have been
introduced:

      Iop_DivModU64to64, // :: I64,I64 -> I128
                         // of which lo half is div and hi half is mod
      Iop_DivModS32to32, // :: I32,I32 -> I64
                         // of which lo half is div and hi half is mod
      Iop_DivModU32to32, // :: I32,I32 -> I64
                         // of which lo half is div and hi half is mod

Patch by Aleksandra Karadzic and Tamara Vlahovic.
