When I do `new void[](n)`, is that buffer allocated with an alignment of 1 or what are the guarantees? How can I set an alignment? Also, is the alignment of any type guaranteed to be a power of 2?
In practice, it's not necessarily a power of 2, but it's *at least* 16 bytes. In general there are very few types (maybe vectors?) that need alignment more than 16 bytes.
The list of bit sizes is currently here: https://github.com/dlang/dmd/blob/82870e890f6f0e0dca3e8f0032a7819416319124/druntime/src/core/internal/gc/impl/conservative/gc.d#L1392-L1414
