[POWERPC] Fix switch_slb handling of 1T ESID values
Now that we have 1TB segment size support, we need to be using the GET_ESID_1T macro when comparing ESID values for pc, stack, and unmapped_base within switch_slb(). A new helper function called esids_match() contains the logic for deciding when to call GET_ESID and GET_ESID_1T. This fixes a duplicate-slb-entry inspired machine-check exception I was seeing when trying to run java on a power6 partition. Tested on power6 and power5.
