MIPS: fix assembler error revealed by clang's debug build

Browse Source 
.set at -  Indicates that macro expansions may clobber
           the assembler temporary ($at or $28) register.
           Some macros may not be expanded without this
           and will generate an error message if noat
           is in effect.

"at" also added to the clobber list.
