Function with error return value bumps @Frame size.

[SrMordred]

const T1 = struct {
    frame: @Frame(T1.func),
    fn func(_: *T1) void {}
};

const T2 = struct {
    frame: @Frame(T2.func),
    fn func(_: *T2) !void {}
};
// @sizeOf(T1));  -> 24
// @sizeOf(T2));  -> 344

Its expected to have this huge bump in size?
