In preparation for the following patch which will fix an issue on the 8xx by re-using the 'slices', this patch enhances the 'slices' implementation to support 32 bits CPUs. On PPC32, the address space is limited to 4Gbytes, hence only the low slices will be used. The high slices use bitmaps. As bitmap functions are not prepared to handle bitmaps of size 0, this patch ensures that bitmap functions are called only when SLICE_NUM_HIGH is not nul.
