I don't think anything is wrong with 'alias set partitioning dependent on SFT
DECL_UIDs'. If two SFTs score equal we need to discriminate them somehow.
DECL_UID is exactly the right thing to use for this.
Note that

* tree-ssa-alias.c (mem_sym_stats): ... here and make it static.

(compare_mp_info_entries): Make sort stable by disambiguating
on DECL_UID.
might have improved the situation. Or worsened it.
The question would be - why should the DECL_UIDs for SFTs change
spontaneously?
