This patch adds the Vector Compare Doubleword instructions introduced
by Power ISA Version 2.07:
- Vector Compare Equal to Unsigned Doubleword (vcmpequd)
- Vector Compare Greater Than Signed Doubleword (vcmpgtsd)

These instructions are encoded with bit 31 set to 1 and so are duals with
vcmpeqfp, vcmpgtfp and vcmpbfp respectively.
The helper macro for integer compares is enhanced to account for 64-bit
operands.

Because of the Power ISA definitions of maximum and minimum
on various boundary cases, the standard softfloat comparison
routines (e.g. float64_lt) do not work as well as one might
think. Therefore specific routines for comparing 64 and 32
