How can I get the alignment of a class instance? I know how to
get the size:
__traits(classInstanceSize, T)
But, there doesn't appear to be any equivalent trait for the
alignment.
There's https://github.com/dlang/druntime/blob/728f1d9c3b7a37eba4d59ee2637fb924053cba6d/src/core/internal/traits.d#L261. But AFAIK, the GC only guarantees an alignment of 16 and doesn't respect any overaligned members or alignment spec for the class.
