compiler assertion failure on empty union and switch statement

[awwdev]

Context

Odin: dev-2022-01:2b918ada The compiler flag check will not produce the compiler assertion. You need to use build (or run).

Current Behavior

u: union {}
switch t in u {
    case: 
}

Odin\src\llvm_backend_general.cpp(1139): Assertion Failure: type_size_of(ut) > 0 Possibly related https://github.com/odin-lang/Odin/issues/1105 (also includes the question if empty unions should be allowed or not)

Expected Behavior

Compilation without problems.
