This patch adds the Divide Doubleword Extended Unsigned
instructions. This instruction requires dividing a 128-bit
value by a 64 bit value. Since 128 bit integer division is
not supported in TCG, a helper is used. An architecture
independent 128-bit division routine is added to host-utils.

This patch adds the Bit Permute Doubleword (bpermd) instruction,
which was introduced in Power ISA 2.06 as part of the base 64-bit
architecture.

Use the new softfloat float32_muladd() function to implement the vmaddfp
and vnmsubfp instructions. As a bonus we can get rid of the call to the
HANDLE_NAN3 macro, as the NaN handling is directly done at the softfloat
level.

Commit e024e881bb provided a pickNaN()
function for PowerPC, implementing the correct NaN propagation rules.
Therefore there is no need to test the operands manually, we can rely
on the softfloat code to do that.
