Please note about the alignment requirements that they are not checked in the 
static analyzer for a reason. To track the alignment data across the data flow, 
probably we should modify the analyzer's core structure (e.g. `MemRegion`) and 
some modeling checkers like the `MallocChecker`. That is not an impossible task 
but also far from easy IMHO (would require several patches built on top of each 
other). Just as an example for the subtleties: think about the nuances of 
`operator new`s default alignment and specific C++17 rules 
(https://reviews.llvm.org/D67545).
