Okay, fixed. To put it in my own words to make sure I understand:
The point of `IndirectRealign` is to get around scenarios where the default
stack alignment is not strict enough for types that have high alignment
requirements. This can happen with `byval` when the data itself is passed on
the stack. However, without `byval` there is no stack alignment we need to
worry about - the copy in the caller should already be aligned. So
`IndirectRealign` is non-applicable.
