Can confirm, that it is fixed in 8.3.0 and 9.2.1.

As written on SO, replacing

asm volatile("" : : "g"() : "memory");

By 

return v.values[capacity - 1];

to avoid the loop being optimised away, leads to the same vectorised code in
7.x as well. So the missed vectorisation, or not inlining size() before
vectorisation causing non-vectorisation due to:

:24:29: note: not vectorized: complicated access pattern.

might be a side effect of the asm volatile() line.
