Coverity is not thrilled about the multiply operations being done in
ger_rank8() and ger_rank2(), giving an error like the following:
Integer handling issues (OVERFLOW_BEFORE_WIDEN)
Potentially overflowing expression "sextract32(a, 4 * i, 4) *
sextract32(b, 4 * i, 4)" with type "int" (32 bits, signed) is evaluated
using 32-bit arithmetic, and then used in a context that expects an
expression of type "int64_t" (64 bits, signed).
Fix both instances where this occur by adding an int64_t cast in the
first operand, forcing the result to be 64 bit.
Fixes: Coverity CID 1489444, 1489443
Fixes: 345531533f ("target/ppc: Implemented xvi*ger* instructions")
