It turned out that I had another local patch which was unexpectedly slowing
this down.

Here is what the unpatched/patched timing looks like without it:

NNN before after

256 0m1.042s 0m0.337s
512 0m6.837s 0m0.887s
1024 0m31.406s 0m4.594s

Sorry about the confusion ...

[There is still another quadratic factor hiding in dwarf2_frame_find_fde,
and it's next on my list.]
