I've now submitted the initial vldN and vstN work, so I thought I'd see
how often it triggers for natty's libav package. I've put some initial
results here:

There are more files to go through, so this isn't complete.
I've also left out cases that were very similar to the ones given.
Some of the code is reasonable, while others are obviously not as good
as they could be. I don't think the problems are really to do with
the vldN and vstN work itself though. They seem to be due to the
underlying interleaved load/store detection, or in the handling
of widening operations.
