MIPS: Use unchecked immediate addition/subtraction
In MIPS assembly there have historically been 2 variants of immediate addition - the standard "addi" which traps if an overflow occurs, and the unchecked "addiu" which does not trap on overflow. In release 6 of the MIPS architecture the trapping variants of immediate addition & subtraction have been removed. In preparation for supporting MIPSr6, stop using the trapping instructions from assembly & switch to their unchecked variants. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
