This GEP would've been used to change the pointer type in the past, but after opaque pointers it's a no-op. I missed removing this in #105545.

Split out from #121577.

This always produces zero offset, regardless of what the struct layout
is.

Originally, this may have been necessary in order to change the pointer type,
but with opaque pointers, it is no longer necessary.
