aurel32 e755699dc7 Always enable precise emulation when softfloat is used
The patch below changes the way to enable softfloat on the PPC target. It
is now enabled when softfloat is used. The rationale behind this change
is that persons who want precise emulation prefer precision over emulation
speed.

aurel32 0ca9d3807c Use float32/64 instead of float/double
The patch below uses the float32 and float64 types instead of the float
and double types in the PPC code. This doesn't change anything when
using softfloat-native as the types are the same, but that helps
compiling the PPC target with softfloat.

It also defines a new union CPU_FloatU in addition to CPU_DoubleU, and
use them instead of identical unions that are defined in numerous
places.
