John Schmidt	00ff123b1e	Sema: fix compile error for switching on undefined union ... Before this fix, passing an undefined union value to `Sema.switchCond` returned an undefined value of the union type, not the tag type, since `Value.unionTag` forwards undefined values unchanged. This leads us into the `.Union` branch in `Sema.zirSwitchBlock` which is unreachable, now we take the `.Enum` branch instead.	2024-02-26 16:51:37 -08:00
