This change aligns globals to the next highest power of 2 bytes, up to a maximum of 128. This makes it more likely that we will be able to compress bit sets with a greater alignment. In many more cases, we can now take advantage of a new optimization also introduced in this patch that removes bit set checks if the bit set is all ones. The 128 byte maximum was found to provide the best tradeoff between instruction overhead and data overhead in a recent build of Chromium. It allows us to remove ~2.4MB of instructions at the cost of ~250KB of data.
