Thanks Dan. Unfortunately the patch breaks things, in the same way Eli's
original patch did. So I fear there's some incorrect transformation being made.
I don't know what and where exactly, but my JIT vector application is
definitely giving wrong output with this patch applied (55995) while the
revision before it is fine.

So I'm reopening this and will further analyze where things go bad.
