The problem was caused by faulty handling of unSSA-able operations on zero-sized data in expand calls, but there is no point to operations on zero-sized data. This CL adds a simplify step to the first place in SSA where all values are processed and replaces anything producing a 0-sized struct/array with the corresponding Struct/Array Make0 operation (of the appropriate type). I attempted not generating them in ssagen, but that was a larger change, and also had bugs. This is simple and obvious. The only question is whether it would be worthwhile to do it earlier (in numberlines or phielem). Fixes #65808.
