powerpc: Add new CPU feature: CPU_FTR_UNALIGNED_LD_STD
Add a new CPU feature bit, CPU_FTR_UNALIGNED_LD_STD, to be added to the 64bit powerpc chips that can do unaligned load double and store double without any performance hit. This is added to Power6 and Cell and will be used in the next commit to disable the code that gets the destination address aligned on those CPUs where doing that doesn't improve performance.
