This is used to ensure that assignments to host-visible memory do not
modify padding bytes in structures and arrays. We decompose
assignments of whole structure and array types into member-wise or
element-wise copies, using helper functions.
This is used in all backends except HLSL, which already decomposes
memory accesses.

Overriding the alignment to 1 would cause nested structures to be
incorrectly laid out. The fix: Don't override the alignment.
All struct layout validation works on the sem offsets, so none of this
has to change.
