FWIW this is always true, and I can't imagine that we would allow a future proposal to make this anything but true.

In #6480 I forgot that StructGet can be signed, which means we need to emit a sign-extend. Arrays already copied the field as part of Array2Struct.

Previously we did not optimize a struct or an array with a packed field. As a result a
single packed field in a struct prevented the entire struct from being localized,
which this fixes. This is also useful for arrays as packed arrays are common (e.g. for
string data).
