target-ppc: Altivec 2.07: Doubleword Compares
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)
  - Vector Compare Greater Than Unsigned Doubleword (vcmpgtud)

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.
