Due to the fact that the x86 port does not support allocating objects on the stack with an alignment that exceeds 8 bytes, we have a rather ugly hack in the x86 code for ChaCha to ensure that the state array is aligned to 16 bytes, allowing the SSE3 implementation of the algorithm to use aligned loads. Given that the performance benefit of using of aligned loads appears to be limited (~0.25% for 1k blocks using tcrypt on a Corei7-8650U), and the fact that this hack has leaked into generic ChaCha code, let's just remove it.
