brw_find_next_block_end() scans through the instructions to find the end of the block. We were calling it for every instruction in the program which is, if you have a single basic block, makes the whole mess a nice clean O(n^2) when it really doesn't need to be. Instead, only call brw_find_next_block_end() as-needed. This brings it back to O(n) like it should have been.
