It can't possibly hurt. If the stack is already aligned on a "better" boundary (64 or 128 bytes), it is also aligned on a 32-byte boundary since 64 and 128 are multiples of 32, and the patch is a no-op. If only a 16-byte alignment is required, a 32-byte alignment wastes a small amount of memory but does not hurt performance. I believe that less-than-16 (and possibly even less-than-32) alignment is pessimal on all platforms we support.
