target-ppc: Bug Fix: mullw
For 64-bit implementations, the mullw result is the 64 bit product
of the sign-extended least significant 32 bits of the source
registers.
Fix the code to properly sign extend the source operands and produce
a 64 bit product.
Example:
R3 00000000002F37A0
R4 41C33D242F816715
mullw 3,3,4
R3 expected : 0008C3146AE0F020
R3 actual : 000000006AE0F020 (without this patch)
