bors f2299490c1 Auto merge of #108106 - the8472:layout-opt, r=wesleywiser 
Improve niche placement by trying two strategies and picking the better result

Fixes #104807
Fixes #105371

Determining which sort order is better requires calculating the struct size (so we can calculate the niche offset). But that in turn depends on the field order, so happens after sorting. So the simple way to solve that is to run the whole thing twice and pick the better result.

1st commit is just code motion, the meat is in the later ones.
