ignore power alignment rule on unions fixes https://github.com/rust-lang/rust/issues/147348 The power alignment rule only applies to the non-first field of a struct, and so should not apply to unions at all. The current code also does not consider enums (whose fields might be, morally, structs). Given that C does not actually have ADTs like this it's probably fine from a compatibility perspective, but I'll leave that to the powerpc folks. cc `@daltenty` `@gilamn5tr` r? compiler
