syssrc/sys/arch/mips/mips: locore_mips1.S locore_mips3.S
Do not save t* registers in syscall stub as suggested by cgd. Saves
a whole 0.01us in lmbench lat_syscall null on our 250Mhz QED system.
$at is still saved just to be safe, although it looks like it does
not need to be. $v1 is used in syscall(), although I'm not sure why.
