Luis Pires a3d67f3e5d target/ppc: fix setting of CR flags in bcdcfsq
According to the ISA, CR should be set based on the source value, and
not on the packed decimal result.
The way this was implemented would cause GT, LT and EQ to be set
incorrectly when the source value was too large and the 31 least
significant digits of the packed decimal result ended up being all zero.
This would happen for source values of +/-10^31, +/-10^32, etc.

The new implementation fixes this and also skips the result calculation
altogether in case of src overflow.
