Maciej W. Rozycki d3a0b96818 MIPS: Use SLL by 0 for 32-bit truncation in `__read_64bit_c0_split' ... Optimize `__read_64bit_c0_split' and reduce the instruction count by 1, observing that a DSLL/DSRA pair by 32, is equivalent to SLL by 0, which architecturally truncates the value requested to 32 bits on 64-bit MIPS hardware regardless of whether the input operand is or is not a properly sign-extended 32-bit value.
