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.

The patch below adds isfinite() and isnormal() functions which can
work with float64 type, used when CONFIG_SOFTFLOAT=yes.

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.

The patch below fixes the computation of FPSCR_VX and FPSCR_FEX when
using the mtfsf instruction. As stated in the PowerPC manual the mtfsf
instruction can't alter those bit, and thus it should always be
computed.
