target-ppc: Clean up mullwo
Simplify the implementation of mullwo. For 64 bit CPUs, the result is
the concatenation of the upper and lower parts of the muls2_i32 operation,
which may be slightly better than deposit. For 32 bit CPUs, the lower part
of the muls_i32 operation is moved into the target GPR.
