chill added a comment. I was just thinking to LGTM it :)
IMHO, the alignment adjustment happens because of C.4 (B.3 indeed leave the HFA/HVA unmodified). > C.4 If the argument is an HFA, an HVA, a Quad-precision Floating-point or > short vector type then the NSAA is rounded up to the next multiple of 8 if > its natural alignment is ≤ 8 or the next multiple of 16 if its natural > alignment is ≥ 16. Browsing the AAPCS HFA and HVA seem always treated the same, and looking at `bool AArch64ABIInfo::isHomogeneousAggregateBaseType(QualType Ty) const` it recognized both FP types and 64- and 128- bit vectors, so we have uniform treatment there as well.
