This patch fixes a bug in the kernel emulation of altivec instructions with
denormalized operands.  The emulation of the vmaddfp and vmnsubfp
instructions was giving the wrong answer because I had the wrong order of
operands to the fmadds and fnmsubs instructions.  This patch fixes it for
both ppc32 and ppc64.
