Comment (by waddlesplash):

 I thought the POSIX specification expects alignment merely to {{{2 *
 sizeof(void*)}}}, so I don't know if we should make that change, it could
 lead to a lot of wasted memory for small allocations.

 This does not appear to be JIT'ed code, so why is there an SSE instruction
 here without an alignment check? Does WebKit specify this buffer will be
 properly aligned? Is there inline assembly being used? GCC is very good
 about using the proper instructions for buffer alignment...
