With the debug counters I have identified the first function where the
difference in behavior of intra-SRA behavior with -g vs -g0 caused the
comparison failure but could not spot any differences in non-debug
statements.

Adding -fno-inline makes the comparison failure go away
(-fno-early-inlining does not help) so at this point I suppose it's
tree-inline that generates different stuff when there are references
to SSA names from debug statements.
