Auto merge of #47007 - eddyb:issue-46897, r=arielb1
rustc: don't use union layouts for tagged union enums. Fixes #46897, fixes #43517 (AFAICT from the testcases). This PR doesn't add any testcases, we should try to at least get perf ones (cc @Mark-Simulacrum). I couldn't find an example in those issues where the choice of LLVM array vs struct (with N identical fields) for padding filler types is still needed, *on top of* this change, to prevent excessive LLVM sinking. r? @arielb1
