Djordje Todorovic 792786e34d [CSInfo][MIPS] Don't describe parameters loaded by sub/super reg copy ...

When describing parameter value loaded by a COPY instruction, consider
case where needed Reg value is a sub- or super- register of the COPY
instruction's destination register. Without this patch, compile process
will crash with the assertion "TargetInstrInfo::describeLoadedValue
can't describe super- or sub-regs for copy instructions".
