1.no longer use register name directly and optimized code format
2.to be compatibal with O32, specify type of address variable with mips_reg and handle the address varialbe with PTR_ operator
3.optimize some unalignment faults in load and store
4.use uld and mtc1 to workaround cpu 3A2000 gslwlc1 bug (gslwlc1 instruction extension bug in O32 ABI)
