SPU LLVM: Use vrangeps in clamp_smax

- This instruction can clamp a value between a range of values, something which previously needed 2 instructions.
- With the immediate byte set to 0x2 it will compute the minimum between the absolute value of the first input and the second input, and then copy the sign from the first input to the result.
