Sorry, I do not have the time on my hands to go and find and parse ABI documents for literally every target triplet LLVM supports, so here’s what I know instead:

- x86_64 SysV - 16 byte aligned;
- x64 (msvc) ABI - 16 byte aligned;
- ARM - 16 byte aligned;
- PPC64 - quadword, so 16 byte;

Sounds intentional enough to me at least.
