ede0c22a67 make @alignOf lazily evaluate the target type
this case works now:

```zig
const Foo = struct {
    field: Bar(@alignOf(*Foo)),
};
fn Bar(comptime alignment: u29) type {
    return struct {
        field: *align(alignment) Foo,
    };
}
```

const b_list: []B = [_]B{};
const a = A{ .b_list_pointer = &b_list };
const obj = B{ .a_pointer = &a };

efdbede7ab breaking: remove field alignment kludge
This breaks behavior tests as well as compile error notes for generic
function calls. However it introduces better circular dependency compile
errors.

The next step is to add Lazy Values to fix the regressions.

81c441f885 remove incorrect assert regarding 128-bit integers
LLVM incorrectly reports 8 as the alignment of i128 on x86_64 but it
correctly reports 16 as the alignment of i128 on aarch64.
