Comment (by tibbe):

 Replying to [comment:3 xnyhps]:
 > The main argument in favor of alignment seems to be: code often
 `memcpy`s string literals into buffers. By doing that with aligned
 addresses (apparently) SSE instructions can be used. This is irrelevant
 for GHC, because the strings are only parsed into `[Char]`s, never copied.

 We avoid going via `[Char]` when creating `ByteString` literals already
 today (using RULES).
