This is the third series of patches to add PowerPC VSX emulation support
to QEMU.

This series adds the floating point arithmetic, compare, conversion and
rounding instructions.  Instructions are implemented using helpers and
wherever practical, existing floating point code such as the softfloat
library and the existing PowerPC floating point helper code.

As with the previous series, the Power ISA V2.06 instructions are added
but the V2.07 instructions are not.  The latter will be implemented in a
future patch series.

V2: Implemented changes based on feedback from Richard Henderson and
Peter Maydell:
     - Included float64_to_uint64() patch in this series rather than just
       cite it as a pre-requesite.
     - Isolated float32_to_uint64() in its own patch.
     - Re-implemented helpers and eliminated the need for some of the proposed
       softfloat routines (float*_is_denormal, float*_get_unbiased_exp).
     - Re-implemented severy helpers so that corner cases (e.g. invalid
       operations) are detected by softfloat.
     - Re-implemented fused multiply-add to use the softfloat muladd routines.
     - Re-implemented the min/max instructions to used the softfloat
       min/max functions.
     - assorted style fixes
