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.]
